Answer: The angle measure for angle 1 would be 98 degrees.

Step-by-step explanation: First, you set 88 equal to (7x+4) since they are vertical angles. (Vertical angles are congruent.) Then you solve and find that x=12. You then plug 12 in to the second equation, (7x-2) and get 82. Since angle 1 is supplementary to the angle that measures 82 degrees, you would take 180-82= Angle 1.

Answer: D

Explanation:

7x + 4 = 88

x = 12

angle 1 = 180 - 7(12) + 2

angle 1 = 98

So it's D
