Answer:
143
Step-by-step explanation:
These are corresponding angles meaning they are congruent. So we just have to set them equal to each other and solve for x. Then plug in x.
7x + 24 = 3x + 92
subtract 3x from both sides
4x + 24 = 92
subtract 24 from both sides
4x = 68
divide both sides by 4
x = 17
Now plug in x to angle A, which is 7(17) + 24
119 + 24
then add
you get:
143
