Question

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

Answer 1

Answer:

• B. sine

Step-by-step 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

Answer 2

GIVEN:

p = y, b = x, h = 11, angle = 47°.

ANSWER:

We will use sin function to find the value of y,

so, sin47° = p/h

sin47° = y/11

y = sin47° × 11

y = 0.73135370 × 11

y = 8.03 or 8.0 rounded.

So, Correct choice - [B] Sine.
