Question

Identify the missing sides.

Answer 1

Answer:

see explanation

Step-by-step explanation:

Use the sine ratio in the right triangle to find the hypotenuse h, and the exact value

sin45° = $\frac{1}{\sqrt{2} }$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{20}{h}$  = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

h = 20$\sqrt{2}$

-----------------------------------------------------------------------------

Use the tangent ratio to find the horizontal leg x and tan45° = 1 , then

tan45° = $\frac{opposite}{adjacent}$ = $\frac{20}{x}$ = 1 ( multiply both sides by x )

x = 20
