Question

HELP!! i dont understand this math question and need help

Answer 1

We know that m<HVT = m<JVS because the mirror projects equal angles. We can claim this about the angle theta.

tan(θ) = 5.8/4

θ =
`tan^(-1)(5.8/4)=55.4` degrees approx.

So, we want sin theta in the other triangle. Luckily, we also know that...

cos(55.4°) x hypotenuse = 36

hypotenuse = 63.4 ft approx.

So we can find the height by evaluating...

sin(55.4°) x 63.4 = 52.2 ft

answer: 52.2 ft

Answer 2

52.2 ft

Explanation:

Triangle JSV is similar to triangle HTV so you have the proportion ...

JS/SV = HT/TV

JS/(36 ft) = (5.8 ft)/(4 ft) . . . . . . . fill in the given values

JS = (36 ft)(5.8/4) = 52.2 ft . . . . multiply by 36 ft

The height of the wall is 52.2 ft.
