Let x and y represent the two angles.
.. x + y = 90 . . . . . . two angles are complementary
.. x -2y = 15 . . . . . . one angle is 15 more than twice the other (y = smaller angle)
Subtract the second equation from the first.
.. (x +y) -(x -2y) = (90) -(15)
.. 3y = 75
.. y = 25
The smaller angle is 25 degrees.
The 60% of the 60 equals 36 after expressed in the fraction of 100, so the answer is 60%.
<h3>What is the percentage?</h3>
It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
Let's suppose the x% of 60 equals 36
So,
x% of 60 = 36
60x/100 = 36
6x/10 = 36
x/10 = 6
x = 60%
Thus, the 60% of the 60 equals 36 after expressed in the fraction of 100, so the answer is 60%.

Answer:
x = 83 degrees
Step-by-step explanation:
35 + 28 = 63
63 + 34 = 97
180 - 97 = 83
