Question

What trig function would you use to find y using 47 angle

Answer 1

sine function

• sinØ=Perpendicular/Hypotenuse
• sin47=y/11
• y=11sin47
• y=8

Answer 2

• B. sine

Explanation:

In the given case you would use sine

• sin = opposite / hypotenuse
• sin 47 = y/11
• y = 11 sin 47
• y = 8.0 (rounded)

Using cosine or tangent you wouldn't be able to find the value of y as the value of x is unknown
