Answer:
Interior Angle Theorem
x=5
measure of angles: 46, 46, 134
Step-by-step explanation:
Interior angle theorem
12x-14=5x+21
7x=35
x=5
12x-14=12(5)-14=46
5x+21=5(5)+21=46
20x+34=20(5)+34=134
It must be about the origin in order to do that
Answer: 1/3
Step-by-step explanation:
X should be equal to four. You divide 35 by 9 to get the answer (x=4)
