GIVING BRAINLIEST! The diagram below shows the measurements of a bookcase. What is the total height of the bookcase?

D. 18 1/8

Step-by-step explanation:

The three 1/3’s add up to 1. The 7 and 9 add up to 16. Add the 1 to that and you get 17. Then change the 1/2 to 4/8 and add that to the 5/8. You then get 1 and 1/8. Then you add that to the 17.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

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.
