Question

M∠A = 25°, a = 22, b = 20

Find: m∠B = ? (rounded to the nearest tenth)
(The triangle is not drawn to scale.)
A) 30.6°
B) 33.2°
C) 35.8°
D) 38.4°

Answer 1

To find m∠B, subtract the measure of angle A from 180 degrees.

Step-by-step explanation:

To find m∠B, we can use the fact that the sum of angles in a triangle is 180°. Since we know that m∠A = 25°, we can find m∠B by subtracting 25° from 180°. Therefore, m∠B = 180° - 25° = 155°.
