Answer: The measure of angle CAB is 38 °
Step-by-step explanation:
To find the measure of CAB, you need to first solve for x.
To solve for x, you need to sum up the two remote interior angles and let them equal to the exterior angle.
The two remoter interior angles are (2 +6x ) and 12x and the exterior angle is 110.
2 +6x + 12x = 110
2 + 18x = 110
-2 -2
18x = 108
x = 6
Angle CAB has the measure of 2+6x and to find the value of the measure input the value of x and solve the expression.
m∠CAB = 2+ 6(6)
m∠CAB = 2+ 36
m∠CAB = 38
