Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Well let’s make it a decimal.
.75 = .84 + Y
So if .84 is more than .75 then subtract
.75 from .84 and you have your answer then convert to fraction
Just took the test, the answer is C.
