Answer:
12 and 4
Step-by-step explanation:
We could set up two equations with the given information.
Let a be the larger number, and b be the smaller number.
4b - 4 = a (Four subtracted from four times the smaller is equal to the larger number.)
2a = 6b (Twice the larger number equals six times the smaller number.)
With the 1st equation, we could substitute a = 4b - 4 into the second equation.
We get
2(4b-4) = 6b
8b - 8 = 6b
2b = 8
b = 4
Substituting back into the first equation,
a = 4(4) - 4 = 12
Therefore the two numbers are 12 and 4.
The angles would be 45° and 60°
