Answer:
x and y are the same. they are both 99
Step-by-step explanation:
65-14=65-5-x
x=9
Explanation=
65-14=65-5-x
51=60-x
-9=-x
9=x
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
