AABC is a right triangle in which zB is a right angle, AB = 1, AC = 2, and BC = v3.
COS Cx sin A=

Answer 1

AC = 13.05 inches

Explanation:

To find AC we use cosine

cos ∅ = adjacent / hypotenuse

AC is the hypotenuse

BC is the adjacent

BC = 10”

cos ∅ = BC / AC

cos 40 = 10/AC

AC = 10/cos 40

AC = 13.05 inches
