It will take 12 years for Benny to reach his moms height.
Benny’s mom: 48
Benny: 12
Half of 48 is 24, so Benny will have to turn 24.
24 - 12= 12
All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:
7x + 4 = 60
7x = 56
x = 56/7 = 8
8y + 12 = 60
8y = 48
y = 48/8 = 6
