The two angles given are two angles of a triangle, so the third angle must be:
SPR=180-RSP-PRS
SPR=66°
The quantity 5 more than a number t is labeled as (5+t)
Product of 9 and the quantity is labeled as = 9(5+t) which equals 45+9t
Result is less than 6 so the equation becomes
45+9t < 6

F(-3) = -12 - 3 = -15
h(2) = -10 + 7 = -3
-15 + (-3)
