X and (4x - 20) are supplementary angles because they add up to 180°. You can tell this because the line which they are formed on is 180<span>°.
Knowing that x + (4x - 20) = 180, you can solve for x:
</span>x + (4x - 20) = 180
(x + 4x) - 20 = 180
5x - 20 = 180
5x = 200
x = 40°

Answer: x = 40°
Answer:
Step-by-step explanation
(2/3) (60/99) = (2/99)(60/3) = (2/99)(20) = 40/99 = .040404......... So.......the sum of the first 15 digits = 7(4) + 7(0) + 0 = 28.
