Question

Triangle ABC is a right triangle and cos(22.6o)=b/13. Solve for b and round to the nearest whole number. Which equation correctly uses the value of b to solve for a? tan(22.6o) = a/13 tan(22.6o) = 13/a tan(22.6o) = a/12tan(22.6o) =12/a

Answer 1

i do not know

Explanation:

Answer 2

cos22.6° = b/13

b ≈ 12

Explanation:

Step 1: Multiply both sides by 13

13cos22.6° = b

Step 2: Plug into calc

You should get 12.0017 as your answer.
