Question

In the figure, angle D measures 127° and angle A measures 75°.

Complete the equation to solve for b, the measurement of angle B.
b = 180° – 75° – (°? – 127°)

Answer 1

The measure of ∠B in triangle ABC is 52°

Triangle

A triangle is a polygon with three sides and three angles. Types of triangles are equilateral, scalene, obtuse, right angled triangle.

From the question:

∠C + ∠D = 180° (sum of angle in a straight line)

∠C + 127 = 180

∠C = 53°

Also:

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

75 + ∠B + 53 = 180

∠B = 52°

The measure of ∠B in triangle ABC is 52°
