You can put this solution on YOUR website! .
The sum of two complementary angles equals 90 degrees.
.
Let x = measure of one of two complementary angles
then
2x+36 = measure of second angle
.
x + 2x+36 = 90
3x+36 = 90
3x = 54
x = 18 degrees
.
second angle:
2x+36 = 2(18)+36 = 36+36 = 72 degrees
.
The two angles are:
18 degrees and 72 degrees
You can put this solution on YOUR website! The two angles are complementary.. that means their sum is equal to 90 degrees.
**
If you choose "X" to be one of the unknown angles, and you are told that one angle is 36 degrees more than twice the other, you can write this as:
(36 + 2x) + x = 90
36 + (2x + x) = 90 (Group like terms)
36 + 3x = 90
3x = 90-36
3x = 54
x = 18 (This is your first angle)
If you subtract 90-18 = 72 (This is your second angle)
Then the angles are 18 and 72!
Hope it helps!
