Part A: Dillon was investigating the time it takes him to enter the water after making the jump from the diving board. He began solving the equation by completing the square and arrived at the following form. -2(t+B)2 + 249/16 what is the value of B?
Part B: How much time does it take Dillon to enter water after the jump from the diving board? round answer to nearest tenth?

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

d 600 because 15*10*2=300

300+300=600
