alright....you can use a equation to solve this question.
Since we know that the two angles are supplementary, they must equal 180 degrees.
Let x represent the first angle.
The second angle is 45 degrees less than two times the measure of the first angle....so.....the second angle is 2x-45
If you put the equation together you will get x+2x-45=180
Now, let's solve:
x+2x-45=180
x+2x=180+45
3x=225
x=225 divided by 3
x=75
Now that you have the degrees of the first angles, you can find out the degrees of the second angle.
second angle=2x-45
=2 multiplied by 75-45
=150-45
=105
Therefore, the first angle is 75 degrees and the second angle is 105 degrees.
(let's check it to be sure)
75+105=180....yay!!!!!
