Answer: x = 20
Step-by-step explanation: We can use the Segment Addition Postulate.
If N is between M and P, then MN + NP = MP.
So we have 2x + 7 + 13 = 3x.
Solving from here, first simplify the left side to get 2x + 20 = 3x.
Now subtract 2x from both sides ti get 20 = x.
So the value of x is 20.
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are

There sum have to be 90 degree. That is

Combining like terms ,

Moving 20 to right side

Dividing both sides by 5

So the measurement of the angles are

Answer:
i think a the fourth attempt
Step-by-step explanation:
8x-13
2(4)=8
2(-5)=-10
-10-3=-13
