Question

Urgent!! Math help!!

Answer 1

Answer/Step-by-step explanation:

Problem 1:

Reference angle = 36°

Opposite = x

Adjacent = 7

Thus, apply trigonometric ratio as follows:

tan 36 = x/7

Multiply both sides by 7

7 × tan 36 = x

x = 5.09 (nearest hundredth)

Problem 2:

Reference angle = 63°

Opposite = 12

Hypotenuse = x

Thus, apply trigonometric ratio as follows:

Sin 63 = 12/x

Make x the subject of the formula

x = 12/sin 63

x = 13.47 (nearest hundredth)
