72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
4) (log3)14/(log3)4
hope dis helps<span />
For Question 1:
angle CAB, angle ABC, angle BCA
Question 2: angle BCD
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
