Lol I think I've explained this enough times now so you know the process
2/6 and 4/6
(just multiplied 1/3 and 2/3 by 2)
Answer:
x = 67; y = 40
Step-by-step explanation:
You are correct with y. Angles y + 23 and 63 are vertical, so they are congruent. That gives you y + 23 = 63, which gives y = 40.
To find x, look at angles 2x - 17 and 63.
They are adjacent angles whose outside rays lie on a line. Angles like these are called a linear pair, and they are supplementary. That means their measures add up to 180 deg.
2x - 17 + 63 = 180
2x + 46 = 180
2x = 134
x = 67
Answer:
4
Step-by-step explanation:
(3 × 14) × 3 = 126
7 × 18 = 126
Multiply num and dem by 2 each to get 8/20
