Answer:
m∠C = 38° (nearest whole number).
Step-by-step explanation:
To find the missing angle, use the Sine Rule.
<u>Sine Rule</u> (for angles)
where:
- A, B and C are the angles
- a, b and c are the sides opposite the angles
Given:
- A = 53°
- a = 18
- c = 14
To find m∠C, substitute the given values into the formula and solve for C:
Therefore, m∠C = 38° (nearest whole number).
