To find the indicated angle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the adjacent side and the hypotenuse. Therefore, we should use cosine to solve.
cos(x) = 12/36
x = cos^-1(12/36)
x = 71 degrees
Hope this helps!
Answer:
You have the two numbers, so 36/60 is the ratio of boys to girls.
Step-by-step explanation:
You will want to simplify those numbers (reduce to lowest terms).
