Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°
Answer:
A. 38
Step-by-step explanation:
Diagonals of a rhombus bisect 90° at the center. Taking O to be the center :
90° + x° + (x +14)° = 180° [Angle Sum Property]2x + 104 = 1802x = 76x = 38Option ARelated Questions

Kendrick was given the equations 4x+2y=14 and 3x-y=23. He decided to solve the system of equations by substitution. Each step is shown.
Step 1: 4x+2y=14
Step 2: 2y=14-4x
Step 3: y=7-2x
Step 4: 3x-7-2x=23
Step 5: x-7=23
Step 6: x=30
In which step did Kendrick make an error? Explain.

The Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Kendrick was given the equations:
Step 1: 4x+2y=14 ...(1)
3x-y=23 ...(2)
From the equation first:
Step 2: 2y = 14 - 4x
Step 3: y = 7 - 2x put this value in the second equation
Step 4: 3x - (7 - 2x) = 23
Step 5: 3x -7 +2x = 23
Kendrick did a mistake in step 4 he did not multiply the term (7 - 2x) with -1
Thus, the Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23

Answer:
B
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FES is an exterior angle of the triangle , then
57° + ∠ F = 142° ( subtract 57° from both sides )
∠ F = 85°
Answer: Option B: 85°
Step-by-step explanation:
Finding E: 142 + 180 + E = 360
360 - 142 - 180 = 32
E = 32
Finding F: 57 + 32 + F = 180
180 - 57 - 32 = 85
F = 85

Answers
Answer:
Step-by-step explanation:
Front and back
Givens
base = 6 feet
height = 2
Formula
Area = 1/2 B * h
Area = 1/2 * 6 * 2
Area = (2) 1/2 * 12
Area = 12 square feet for both front and back
Base
The base is a rectangle. A rectangle has the formula of Area = L*w
Givens
L = 10 feet
W = 6 feet
Area = 10 * 6 = 60
Left roof
The left roof is also a rectangle. Area = L*w
Givens
L = 10 feet
W = 3 feet
Area = 3 * 10 = 30 feet^2
Right Roof
The right roof is a rectangle. Area = L*w
Givens
L = 10 feet
w = 4 feet
Area = 4 * 10 = 40 ft^2
Total area
Total Area = right roof + left roof + Base + front and back
Total Area = 40 + 30 + 60 + 12
Total Area = 142 feet ^2

Step-by-step explanation:
Converting km/h ⇒ m/s :
⇒ 54 km/h x 5/18
⇒ 3 x 5
⇒ 15 m/s
===============================================================
Formula to calculate the angle :
⇒ tanθ = v/r
⇒ tanθ = (15 m/s)/(20 m)
⇒ θ = tan⁻¹ (0.75)
⇒ θ = 37°
=============================================================
Converting to radians :
⇒ Radian measure = Angle measure × π/180°
⇒ Radian measure = 37° × π/180°
⇒ Radian measure = 37π/180 radians

Answer:
The radius is 8.
Step-by-step explanation:
Because OA is a radius and AB is a tangent, Angle A is a right angle. So you can use Pythagorean theorem (shortcut Pythagorean triple)
OA^2 + 15^2 = 17^2
OA^2 + 225 = 289
OA^2 = 64
OA = 8
OA is a radius, the radius = 8

How many hours and minutes is 125 minutes
Answers
Answer:
2 hours and 5 minutes.
Step-by-step explanation:
2 hours is 60mins+60mins which is equal to 120mins and then the extra 5mins
Hilary studied for a total of 2 hours and 5 minutes this week.
If Hilary studied for 25 minutes each day for five days this week, we can calculate the total study time by multiplying the number of minutes studied per day (25) by the number of days (5):
25 minutes/day × 5 days = 125 minutes
To convert this to hours and minutes, we need to divide the total minutes by 60 (since there are 60 minutes in an hour) to get the number of hours and find the remainder as minutes.
125 minutes ÷ 60 = 2 hours and 5 minutes
Therefore, Hilary studied for a total of 2 hours and 5 minutes this week.

Axel used the vertical line test on this graph, and decided it is a function because the vertical line only passes through one point, (3, 0).
On a coordinate plane, a circle is centered around (0, 0). A vertical line touches the edge of the circle at (3, 0).
Is Axel’s statement correct?
Answers
Explanation:
By viewing this question, I can already tell Axel is incorrect. Because the shape is a circle, it goes around and then meets back at one spot. Therefore, when using the vertical line test, many different points have the same y-value. Because there are multiple outputs for one value, this circle is not a function. Axel’s graph does not pass the vertical line test for every set of points.
Answer: Axel's statement would be incorrect. (If this is for Edgenulty, the answer is C)
Step-by-step explanation: No, because the relation does not pass the vertical line test for every possible input.
