For the last on you need to set up a proportion with the degrees. You know the arcs add to 360 and that small section is 120 so you set it equal to x over the entire area. X is the answer. The formulas are next to all answers

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.

An angle in standard position measures 5п 8 radians. In which quadrant does the terminal side of this angle lie? O Quadrant I II

user100 [1]

Answer:

I've attached a picture of a unit circle with the quadrant labeled.

Calculate the degree of 5п 8 radians:

$\frac{5\pi }{8} =\frac{5*180}{8} =\frac{900}{8} =112.5$

Locate the general location of 112.5° on the unit circle:

It's between 120°( $\frac{2\pi }{3}$ ) and 90°( $\frac{\pi }{2}$ ).

Find the quadrant it lies in:

Quadrant II
