Original equation x = yz / a solve for a
xa = yz
a = yz / x
60°, 120° and 180° are the angles at which it will map onto itself.
X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78

Answer:
Mikhail is 25 and Gabrielle is 15
Step-by-step explanation:
g = (m-10) and g+m = 40
We'll substitute that first equation into the second
(m-10) + m + 40
2m - 10 = 40
2m = 50
m = 25
