Answer:
x = 11.1
Step-by-step explanation:
Cosine theta = adjacent/hypotenuse
cos 42 = x/15
x = 15 cos 42
x = 11.1
M(x) = 2x^2 + 6x - 7.......find m(3) by subbing in 3 for every x
m(3) = 2(3^2) + 6(3) - 7
m(3) = 2(9) + 18 - 7
m(3) = 18 + 18 - 7
m(3) = 29 <==
6 foot =850
850÷6=141.667
then for 12 section
141.667x 12=1700 or
you find the ratio of 6:12
= 1:2
therefore 2×850=1700
