The value of the angles is 38° and 52°.
Given that,
Based on the above information, the calculation is as follows:
a = 2(b - 12)
= 2b - 24
We know that the angle in an acute angle should be equivalent to the 90 degrees.
So,
a = 90 - b.
Given
a = 2b - 24
Now
90 - b = 2b - 24
2b + b = 90 + 24
3b = 114
b = 38
So,
a = 90 - 38
= 52
Therefore we can conclude that the value of the angles is 38° and 52°.
