Let x be the measure, in degrees, of the smaller acute angle.
If the measure of the larger acute angle is 15%5Eo more than twice that,
the measure of the larger acute angle, in degrees, is
2x%2B15
In a right triangle, the measures of both acute angles add up to 90%5Eo, so
x%2B2x%2B15=90
first we solve for x, the measure, in degrees, of the smaller acute angle:
x%2B2x%2B15=90 --> 3x%2B15=90 --> 3x%2B15-15=90-15 --> 3x=75
--> 3x%2F3=75%2F3 --> x=25
The measure of the larger acute angle, in degrees, is
2x%2B15=2%2A25%2B15=50%2B15=highlight%2865%29
or 90-25=highlight%2865%29
The larger acute angle measures highlight%2865%5Eo%29 .
