Question

I am needing help. I do not understand these types of problems.

Answer 1

For angle 45 degree, hypotenuse side is 15 and base side is x.

Determine the measure of side x by using trigonometry.

`\begin{gathered} \cos 45=(x)/(15) \\ 0.707=(x)/(15) \\ x=15\cdot0.707 \\ =10.605 \end{gathered}`

Thus value of x is 10.605 m.

Answer: x = 10.605 m
