Question

HELP PLEASE

Answer 1

Find the measure of F if D =88

Answer 2

its a right angle triangle right?

Answer 3

use simple trigonometry.

Since both these triangles are equal we can then use 40degree because it's same on the other triagle

Answer 4

now we need to find the value of f which could be solved as \[\cos40^{0}=\frac{ f }{ 88 }\]\[x= 88 \times \cos40^{0} = 67.4\]

Answer 5

got it?

Answer 6
