Question

Please someone help me with this ASAP especially with the workout!!

Answer 1

Answer:

78°

Step-by-step explanation:

From the diagram,

Applying sine rule,

SinA/a = sinC/c................... Equation 1

Given: c = 29 cm, C = 50°, a = 37 cm

Substitute into equation 1 and solve for A.

sinA/37 = sin50°/29

sinA = (37×sin50°)/29

sinA = (37×0.766)/29

sinA = 28.34/29

sinA = 0.9774

A = sin⁻¹(0.9774)

A = 77.8°

A ≈ 78°

Hence the measure of angle A = 78°
