its the 3rd answer i think
I think you meant to have more of a problem stated.
Basically, you use the Law of Sines when you have 2 angles but the length of only one side.
The formula for this law is
a / sine(A) = b / sine(B) = c / sine(C)
Answer:
A. 81
Step-by-step explanation:
F(x)=
if x=4, then F(4) =
= 3×3×3×3=81
Answer: see attachments
<u>Step-by-step explanation:</u>
Use Pythagorean Theorem to find the missing side (x² + y² = h²)
Use the following formulas to find the trig functions:

Answer:

Step-by-step explanation:
Given
The attached triangle
Required
Length AB
To do this, we make use of sine law which is represented as:

So, we have:

Make AB the subject
