Answer:
Step-by-step explanation:
x=3
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:
The number would be 2.
Step-by-step explanation:
I set up an equation 5x+3, and x. So since it's a difference we know that we have to subtract, so I subtracted the two expressions, and set that equal to 11.
Solve 5x+3-x=11
Answer 4x=8, x=2
