Question

4. The figure represents a ramp. Find the height of the ramp.

Answer 1

Answer:

the answer is the option D

$8\ m$

Step-by-step explanation:

we know that

The figure of the ramp represent a right triangle

Applying the Pythagoras Theorem

Let

h------> the height of the ramp

$17^{2}=15^{2}+h^{2}$

solve for h

$h^{2}=17^{2}-15^{2}$

$h^{2}=64$

$h=8\ m$

Answer 2

Notice that the triangle is a right triangle, because of the right angle. By the Pythagorean Theorem, $a^2+b^2=c^2$. Then $15^2+b^2=17^2\implies 225+b^2=289\implies b^2=64\implies b=8$, d. 8 m
