Answer:
m∠B = 70.0° (nearest tenth)
Step-by-step explanation:
<u>Sine Rule for Angles</u>
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Given:
- a = 13
- c = 19
- A = 40°
Substituting the given values into the formula to find m∠C:
Interior angles of a triangle sum to 180°
Therefore, m∠B = 70.0° (nearest tenth)
