Question

1. What is the value of H? (1 point)A. 4B. 8√3C. 16D. 8√2​

Answer 1

Answer:

D

Step-by-step explanation:

Using the sine ratio in the right triangle

noting that sin45° = $\frac{1}{\sqrt{2} }$ ← exact value

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{8}{h}$

Multiply both sides by h, then

h ×$\frac{1}{\sqrt{2} }$ = 8

Multiply both sides by $\sqrt{2}$

h = 8$\sqrt{2}$ → D
