If you are solving for x, then x=52
well, a right-triangle has 90° total, so if one of the acute angles is taking up 74°, then the other is just 90° - 74°.
Let the age of Brandon be x.
Therefore the age of Michael is 4x
Also the age of Michael is 27+x
So
4x=27+x
3x=27
X=9
Brandon age is 9years while Michael's age is 36
