A wooden ramp is placed against wall.The top of the ramp is 7.5m above the bottom of the wall.The bottom of the ramp is 10m away from the bottom of the wall.what is the length of the ramp?
Answers
The wooden ramp forms right angle triangle when rested against wall
Given 7.5m above ground which is height of right angle triangle
10m away from bottom of wall which is base of triangle
now ramp is hypotenuse...and its height be 'H'
using Pythagoras theorem,
H^2=(7.5)^2+(10)^2
H=12.5m
Answer:
12.5 m
Step-by-step explanation:
The ramp forms a right-angled triangle with the wall and the ground.
To find the length of the ramp, we have to find the square root of the sums of the squares of the length of wall and distance b/w wall and ramp from ground according to pythagorean theorum .
(Length of wall) ² + (Distance on ground) ² = (Length of ramp) ²
(7.5) ² + (10)² = (X)²
56.25 + 100 = X²
156.25 = X²
√ (156.25) = X
12.5 = X
Therefore, Length of the ramp is 12.5 m
