Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)
Supplementary angles - when the sum of their degree measure is 180°
8x - 13 + 4x + 1 = 180
12x = 192
x = 16
Answer:
16
Step-by-step explanation:
angle 6 and angle 3 are supplementary angles
that means added together, they equal 180
so 8x-13 + 4x+1=180
12x-12=180 simplify by adding and subtracting
12x=192 simplify by adding 12
x=16 divide 192 by 12

9.0 Happy to help! Have a nice day!
(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
