The measure of a straight angle (2x+50) (6x+2)

see below

Step-by-step explanation:

If the two angles form a straight angle, their sum is 180

2x+50 + 6x+2 = 180

Combine like terms

8x + 52 = 180

Subtract 52 from each side

8x+52-52 = 180-52

8x = 128

divide each side by 8

8x/8 = 128/8

x = 16

2x+50 = 2 (16) + 50 = 32+50 = 82

6x+2 = 6 (16) + 2 = 96+2 = 98
