Answer:
Below in bold.
Step-by-step explanation:
x^2 - y^2 = 11
2x^2 + y^2 = 97
From the first equation:
y^2 = x^2 - 11
Substituting in the second equation:
2x^2 + x^2 - 11 = 97
3x^2 = 108
x^2 = 36
x = 6, -6.
Substituting for x in the first equation:
(6)^2 - y^2 = 11
y^2 = 36 - 11 = 25
y = 5, -5.

Answer:
m∠O = 105°
Step-by-step explanation:
Step 1: Set up equation
x + 40 + 3x = 180
Step 2: Solve
4x + 40 = 180
4x = 140
x = 35
Step 3: Plug in
3(35) = 105°
And we have our answer!
The answer is actually 15.
