A ball is thrown from an initial height of 3 meters with an initial upward velocity of 15 m/s. The ball's height h (in meters) after t seconds is given by the following.

Find all values of for which the ball's height is 8 meters.
Round your answer(s) to the nearest hundredth.

t = seconds ​

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
