It is given in the question that
The measure of one angle is 15 less than half the measurement of its supplement.
Let the measurement of supplement angle is x degree.
So the measurement of the other angle is
![\frac{x}{2} -15](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%20-15)
And the sum of the measurement of supplementary angles is 180.
![x+ \frac{x}{2} -15 =180 \\ \frac{3x}{2} = 195](https://tex.z-dn.net/?f=x%2B%20%5Cfrac%7Bx%7D%7B2%7D%20-15%20%3D180%0A%5C%5C%0A%5Cfrac%7B3x%7D%7B2%7D%20%3D%20195)
Multiplying both sides by 2
![3x = 390 \\ x = 130](https://tex.z-dn.net/?f=3x%20%3D%20390%0A%5C%5C%0Ax%20%3D%20130)
So one angle is of measurement 130 degree and the other angle is of measurement 50 degree.
Answer:
your answer is 1-4x
Step-by-step explanation:
first multiply 3 with X+2 and 5 with 2x+1
and simply them
First determine how much it increased by. 36+X=64
X=28
It increased by 28
Now determine what percentage 28 is of 36
36(Y)=28
Y=.77777778
28 is a 77.78% (.7778) increase from 36
After you round, your answer is 78%
