Question

Based on the picture below: Solve for AB

Answer 1

Answer:

AB ≈ 35.93

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos3.5° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{AB}{36}$

Multiply both sides by 36

36 × cos3.5° = AB, thus

AB ≈ 35.93 ( to 2 dec. places)
