Question

The measure of Angle b is 40 degrees and the measure of angle c is 66 degrees. What is the measure of angle a?

Answer 1

ANGLE A=74

Explanation:

LET ANGLE A BE X

ANGLE B=40°

ANGLE C=66°

SUM OF ADJACENT ANGLE IS 180°

SO, WHEN:

40+66+X=180

X=180-106

ANGLE A=74°

HAVE A NICE DAY!!

Answer 2

74

Explanation:

All the angles of a triangle add up to 180

66+40 = 106

To find the missing angle...

180-106 = 74
