Step-by-step explanation:

Given c = longest of triange = 15m

Given b = short side of triangle = 9m

By pythagoras' Theorem,

${c}^{2} = {a}^{2} + {b}^{2} \\ {a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {(9)}^{2} = {(15)}^{2} \\ {a}^{2} + 81 = 225 \\ {a}^{2} = 225 - 81 \\ {a}^{2} = 144 \\ a = \sqrt{144} \\ = 12m$

If the top of a 4.50 m ladder reaches twice as far up a vertical wall as the foot of the

STALIN [3.7K]

Answer:

4 m.

Step-by-step explanation:

Length of ladder, L = 4.50 m

Base of ladder from the wall, B = x

Height of the wall, H = 2x

Using Pythagoras theorem

$L^2 = B^2 + H^2$

$4.5^2 = x^2 + (2x)^2$

$5x^2 = 4.5^2$

$x = 2\ m\ (approx.)$

Height of the wall is equal to 2 x 2 = 4 m.
