1/5 x 25X - 1/5 x 75 + 9= 1/4 x 8X + 1/4 x 36
5X - 15 + 9 = 2X + 9
5X - 2X = 9 - 9 + 15
3X = 15
X= 15/3 = 5
Answer:
(6,-2)
Step-by-step explanation:
The sum of the two acute angles is 90 degrees. Set this up in the form of the following equation.
We know this because the two angles are x and 3x + 12.
From here you just need to solve.
, or 19.5
This is the measure of one angle. The measure of the other angle is therefore, after a few calculations, 70.5.
19.5 degrees, 70.5 degrees.
