Question

In △Rst, the measure of

Answer 1

Explanation:

You might just duh me but the answer is obviously less than 7.7 but greater that anything above one so what you do is process of elimination hope this way of solving helps

Answer 2

∠ R ≈ 53°

Explanation:

Using the sine ratio in the right triangle

sin R =
`(opposite)/(hypotenuse)` =
`(ST)/(SR)` =
`(7.7)/(9.7)` , thus

∠ R =
`sin^(-1)` (
`(7.7)/(9.7)` ) ≈ 53° ( to the nearest degree )
