Answer:
The value of x is 8
The measure of angle A is 42 degrees
A and B are consecutive interior angles
Step-by-step explanation:
Since A and B are consecutive interior angles you combine both equations and have it equal to 180
16x+10+5x+2=180
21x+12=180
21x=168
x=8
Plug 8 into the equation across from A
16(8) +10
128+10
138 degrees
Since angle A is supplementary you do 180-138= 42 degrees
