Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:
A support structure is shown in which a right triangle PQR is formed with the right angle at Q.
Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)
Part B: The length of rod PR is adjusted to 17 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
Answer:
Part A: 2 * sqrt(65) ft, or about 16.12451549... ft
Part B: sqrt(93) ft, or about 9.64365076... ft
Step-by-step explanation:
Part A: A right triangle is formed, so we can use the Pythagoren theorem to solve for the length of rod PR. The Pythagoren theorem is a^2 + b^2 = c^2, with PR being c^2, and PQ and QR being a^2 and b^2 (interchangeably). So, we plug in the lengths and get the equation 14^2 + 8^2 = c^2. This is equal to 144 + 64 = c^2. Simplified, we have 208 = c^2. Getting the square root of both sides, we find that c is equal to approximately 16.12451549... feet.
Part B: Now we are solving for a side length rather than the hypotenuse. We can use the Pythagorean theorem here too. We have: a^2 + 14^2 = 17^2. We solve and get a^2 + 144 = 289. Simplified, a^2 = 145. The square root of 145 is approximately 9.64365076... feet, our answer.

A. p> a
B. p
O c. p= 9
D. Can't be determined
The value of p is equal to q from the given triangles
Sum of interior angle of a triangleThe sum of interior angle of a triangls is 180 degrees
For the first triangle
p + 60 + 30 = 180
p + 90 = 180
p = 180 - 90
p = 90 degrees
For the second triangle
q + 45 + 45 = 180
q + 90 = 180
q = 90degree
From both results, you can see that the value of p is equal to q

A soccer field measures 90 meters wide by 120 meters long starting together in one corner you walk the diagonal to the opposite corner while your friend walks the length and with to get the same corner how much further dose your friend walk
Answer:
The friend walks 60 m further than the other person
Step-by-step explanation:
Given the dimensions of the soccer field:
Width = 90 m
Length = 120 m
One person walks along its diagonal.
As the length and width of the field are perpendicular, Diagonal can be calculated using Pythagorean Theorem:
[tex]Diagonal ^2 =Length^2+Width^2[/tex]
[tex]Diagonal ^2 =90^2+120^2\\\Rightarrow Diagonal ^2 =8100+14400\\\Rightarrow Diagonal ^2 =22500\\\Rightarrow Diagonal =150\ m[/tex]
So, the distance walked by the person along the diagonal = 150 m
Distance walked by the person's friend to reach the opposite point = Width + Length = 120 + 90 = 210 m
So, the difference of the two distances will give us the distance that was walked further by the friend.
The difference is = 150 - 90 = 60 m
So, the friend walks 60 m further than the other person.

Which are necessary conditions to apply the SAS Triangle Congruence Theorem? Select all that apply.
A. Two sides and the included angle of a triangle are congruent to the corresponding parts of another triangle.
B. Two angles and the included side of one triangle are congruent to the corresponding parts of another triangle.
C. An angle and the two sides collinear with the angle's rays are congruent to the corresponding parts of another triangle.
D. Two sides and any angle of one triangle are congruent to the corresponding parts of another triangle.
Answer:
A and C
Step-by-step explanation:
Two sides and the included angle of a triangle are congruent to the corresponding parts of another triangle.
An angle and the two sides collinear with the angle's rays are congruent to the corresponding parts of another triangle.
The statements that will apply that meets the conditions for two triangles to be considered congruent to each other by the SAS Congruence Theorem are:
A. corresponding two sides and an included angle that are congruent in both triangles
C. A pair of two sides that are collinear to an angle's ray and an angle, which are congruent to the corresponding two sides and angle in the other triangle.
Recall:
SAS Triangle Congruence Theorem states that if two triangles have a pair of corresponding two sides and an included angle that are congruent to each other, then the two triangles are considered congruent to each other.The image shows two triangles that are congruent by the SAS Congruence Theorem.Therefore the statements that will apply that meets the conditions for two triangles to be considered congruent to each other by the SAS Congruence Theorem are:
A. corresponding two sides and an included angle that are congruent in both triangles
C. A pair of two sides that are collinear to an angle's ray and an angle, which are congruent to the corresponding two sides and angle in the other triangle.

What is the equation of the line in slope-intercept form?
Answer:
y=3/5x+3
Step-by-step explanation:
The first blank is the slope. To find the slope, you first get 2 points on the graph. I chose (-5,0) and (0,3). You then find the difference in the Y values, which is positive 3, and find the difference in the X values, which is 5. Slope is y/x, so the slope would be 3/5. The second blank is the y-intercept, which is where the line meets the y value with an x value of 0. The y-intercept would be 3.

a the difference of 17 and 9
Answer:
A.

A pumpkin is thrown out of a window that is 4 feet high with an upward velocity of 14. When will the pumpkin hit
the ground?
A. 0.4 seconds
OB. 1.1 seconds
O c. 7 seconds
OD. 0.22 seconds
Answer:
Step-by-step explanation:
Given
Height H = 4 feet
Velocity = 14ft/s
Required
Time the pumpkin will hit the ground
Using the equation of mottion
H = ut + 1/2gt²
4 = 14t + 1/2(9.8)t²
4 = 14t + 4.9t²
4.9t²+14t-4 = 0
t = -14±√196+16(4.9)/2(4.9)
t = -14±√196+78.4/2(4.9)
t = -14±16.57/9.8
t = -14+16.57/9.8
t = 2.57/9.8
t = 0.2seconds
