Circle o is shown. 2 secants intersect at a point outside of the circle to form angle 1. the first arc formed is d, and the second arc formed is b. arcs a and c are the other 2 arcs outside of the secants.
which equation is correct regarding the measure of ∠1?

m∠1 = one-half(a – c)
m∠1 = one-half(a + c)
m∠1 = one-half(b – d)
m∠1 = one-half(b + d)

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
