2X^2+22x+318=1270
2x^2+22x-952=0
x^2+11x-476=0
(x+28)(x-17)=0
x=17
X=30 degrees for each of the congregant angles

Answer:
26.3 hours
Step-by-step explanation:
We need to divide 250 by 9.50, therefore we get the answer ≈ 26.3
Angle D and angle G are the base angles, which means they are equal. If D = 18, then G = 18. Since the sum of the angles of a triangle equals 180 degrees, subtract 18 + 18 from 180 to get angle O.
180 - 36 = 144
Angle O = 144
Hope this helps =)
