Answer 1

Answer:

C. 31.64

Step-by-step explanation:

23 = sin(36) × Hypotenuse

Hypotenuse is the baseline between the angles 36° and 54°.

Hypotenuse = 23/sin(36)

x = cos(36) × Hypotenuse

x = cos(36) × 23/sin(36) = cos(36)/sin(36) × 23 =

= 1/tan(36) × 23 = 23/tan(36) = 31.63686382... ≈

≈ 31.64
