Answer:
Step-by-step explanation:
The two acute angles add up to 90 degrees. That's because every triangle has 180 degrees and a right angle is 90 degrees.
<m1 + <m2 + 90 = 180                   Subtract 90 from both sides.
<m1 + <m2 + 90 - 90 = 180 - 90   Combine
<m1 + <m2 = 90
Let m1 = 9*m2                                Substitute.
9m2 + m2 = 90                              Combine
10 m2 = 90                                     Divide by 10
10m2/10 = 90/10
m2 = 9
m1 = 9*m2
m1 = 9 * 9
m1 = 81
The right angle = 90
m1 = 81
m2 = 9
