A 20 foot ladder leans against a house the base of the ladder is 12 feet from the house. What is the distance from the ground to the top of the ladder?
Answers
Answer:
16ft
Step-by-step explanation:
Please see attached diagram depicting the above scenario.
Since the ladder leans against a house, then it forms a right angled triangle while the hypothenus is 20 foot, the distance of the base of the ladder is 12 feet from the house, hence we are required to find the point at which the ladder touches the house I.e height, rep by h.
We will apply Pythagoras theorem to solve the problem.
h^2 = 20^2 - 12^2
h^2 = 400 - 144
h^ 2 = 256
h = √256
h = 16ft
Hence, the distance from the ground to the top of the ladder is 16ft.

Answer:
V = 3
Step-by-step explanation:
4(v + 2) = 20 we must first distribute
4v + 8 = 20 we subtract 8 from both sides
4v + 8 - 8 = 20 - 8 we simplify that
4v = 12 we divide both sides by 12 to isolate v

O Vertical translation up by 5 units
O Vertical Translation down by 5 units
Vertical stretch by a factory of 5
O Reflection over the X – axis
10t
Answers
Answer:
Vertical translation up by 5 unitsExplanation:
From vertex form of quadratic function g(x)=a(x-h)²+k the h and k are coordinates of vertex transformed from point (0,0) which is the vertex of parental function f(x)=ax²
It means the h determines how many units we moved parental graph horizontaly (to the left if h<0, to the right if h>0) and the k determines how many units we moved parental graph verticaly (down if h<0, up if h>0)
g(x) = (x - 8)² + 5 ⇒ h = 8, k = 5
So if h and k are >0 it means the parental graph was moved to the right and up.
The length of the base on an
isosceles triangle is 5x. The length of
a leg is 6x + 8. The perimeter of the
triangle is 107. Find the length of the
base.
Answers
Answer:
455/17 or 26 13/17
Step-by-step explanation:
Since the triangle is an isosceles triangle the legs are the same length.
2(6x+8) + 5x= Perimeter
12x+16+5x= Perimeter
Perimeter =107
17x=107-16
17x=91
x=91/17
Since we are trying to find the base which is 5x, we can substitute.
5*91/17= 455/17 or 26 13/17

Answers
Answer:
125°
Step-by-step explanation:
Sum of all the internal angles in a triangle is 180°
So, we have,
67°+58°+ Adjacent angle of 1 = 180°
125°+Adjacent angle of 1 = 180°
Adjacent angle of 1 = 180° - 125° = 55°
Angle 1 and its adjacent angle are supplementary
So, Angle 1 + Adjacent angle of 1 = 180°
Angle 1 + 55° = 180°
Angle 1 = 180° - 55° = 125°
