Answer:
x=9 and angle B = 40°.
Step-by-step explanation:
Since angles A and B are corresponding angles, they both equal one another. Your equation should be set up like this:
5x-5° = 3x+13°
Once you solve for x, you'll get 9.
To solve for angle B, plug the value of x in the equation:
3(9)+13°
27+13°
Angle B = 40°.
