The answer to the question is 108
It would be 225+400=c^2. square both sides to result in 25.
Answer:
The answer is -2, -17
Step-by-step explanation:
You write a system of equations

Then you solve:
-2, -17
Total angle sum will always equal 360 degrees. Due to vertical angles theorem, we know the angles opposite the polynomials also equal the polynomials. So, we can double both of them (like solving for perimeter) and sum them to 360.
Thus, 360 = 2(2x + 10) + 2(x+ 5)
360 = 2(2x + 10 + x + 5)
360 = 2(3x + 15)
180 = 3x + 15
165 = 3x
x = 55
