Help with questions 10-11

10. x=15 degrees

11. x=10 degrees

Step-by-step explanation:

For these triangles inscribed in the circle, the top angle is always 90 degrees. Because of this, we can subtract 90 degrees from 180 degrees and be left with 90 degrees. For problem 10, 30+4x=90, so x=15. For problem 11, 4x+5x=90, so x=10

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

is there a question here?
