Answer:
95 degrees
Step-by-step explanation:
1/2 of a circle is 180 and 180-103=77 and on the other half 72 + 13= 85 and add THAT TO 103 to get 188+77= 265 and 360-265= 95
The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
