If a = 7, b = -3 and c = 2, the 2nd degree equation that corresponds to these coefficients is: a) 2x(x+1) + 5x² - 5x = - 2
b) 2x² + 7x - 5 = 0
c) 3x² -7 = 0
d) 4(x² + 7) - 3x - 7 = 0
e) None of the above.

the answer is (-4,-4)

hope this ! : d

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
