$\text{ Hello there! :)}$

$\large\boxed{w(h(x)) = 4x+ 7}$

$w(h(x) = \\\text{Substitute in the equation of h(x) into "x" of the equation w(x):}\\\\w(h(x)) = 4(x + 1) + 3\\\\\text{Simplify:}\\\\w(h(x)) = 4x + 4 + 3\\\\w(h(x)) = 4x + 7$

Kayson is looking at two buildings, building A and building B, at an angle of elevation of 40' Building Als 120 feet away, and b

-BARSIC- [3]

Answer:

A. Building A, it is around 100.69 feet taller than building B.

Step-by-step explanation:

Since building A is 120 feet away at and elevation of $40^{0}$ , then:

Tan $40^{0}$ = $\frac{x}{120}$

Where x is the height of the building at the horizontal plane.

x = Tan $40^{0}$ × 120

= 100.692 feet

For building B at the same elevation,

Tan $40^{0}$ = $\frac{x}{60}$

x = Tan $40^{0}$ × 60

= 50.346 feet

Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
