Answer 1

AB = 8.39 inches

AC = 13.1 inches

(corrected to 3 significant figures.)

Explanation:

In a right triangle, AB is the opposite side; BC is the adjacent side, and AC is the hypotenuse side.

since tanθ = opposite / adjacent,

we can use this to find side AB.

tan40° = AB / 10

AB = 8.39 in. (corrected to 3 significant figures.)

since cosθ = adjacent / hypotenuse

we can use this to find AC.

cos40° = 10 / AC

AC = 13.1 in. (corrected to 3 significant figures.)

Answer 2

AB= 8.4

AC= 13.1
