If every story in a building was 15 high how high would be a 10 story building

150 units.

Step-by-step explanation:

Every story is 15 units high.  There are 10 stories.

to find this answer I multiplied 10 by 15 because there are 10 stories, each one 15 units high.

10 x 15 =150

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.
