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:
ANGLE A=74
Step-by-step 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:
74
Step-by-step explanation:
All the angles of a triangle add up to 180
66+40 = 106
To find the missing angle...
180-106 = 74
