Answer:

Step-by-step explanation:

f(x) -h(x) = x³ + 2x² -7x - 8 - [4x² - x - 15 ]

= x³ + 2x² - 7x - 8 - 4x² + x + 15

= x³ + 2x² - 4x² - 7x + x - 8 + 15

= x³ - 2x² - 6x + 7

Using the SSA formula:

X = SQRT ( 40^2 + 26^2 - 2*40*26*cos(65))

X = SQRT(2276 - 2080*cos(65))

X = SQRT(1396.954)

X = 37.37 = 37.4 ft.
