Lines Line A E and Line G H are parallel in the image below. The image will be used to prove that the sum of the measures of the
interior angles of Triangle C G H is 180°. Lines A E and G H are parallel. Angles F and C are congruent.
Which statement would be included in the proof of why Measure of angle C + measure of angle G + measure of angle H = 180 degrees.?
Angles F and H are congruent.
Angles C and E are congruent.
Angles A and G are congruent.
Angles F and C are congruent.
F(x)=-5t^2+20t+60 Divide everything by -5 f(x)=t^2-4t-12 (t-6)(t+2) Set it up to zero t-6=0. t+2=0 t=6. t=-2 Since you can’t have negative seconds, the answer is 6 seconds
