Question

Use trigonometry to find the unknown side (round to 1 decimal)​

Answer 1

Answer:

1 1 1 1

Step-by-step explanation:

Answer 2

Answer:

a = 7.5

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{a}{15}$ = $\frac{1}{2}$ ( cross- multiply )

2a = 15 ( divide both sides by 2 )

a = 7.5
