Question

Which function would you use to solve for the length b?

a. a times tan(B) = b
b. a/tan(B) = b
c. c times sin(A) = b
d. c/cos(A) = b

Answer 1

To solve for the length b in a right triangle, you should use the trigonometric function tangent (tan) of angle B.

Step-by-step explanation:

To solve for the length b in a right triangle, we can use the trigonometric function tangent (tan) of angle B. So the correct function to use is option a, which is: a times tan(B) = b. This is because the length a is the adjacent side to angle B, and tangent is defined as the ratio of the length of the opposite side to the adjacent side in a right triangle.
