I think it was a trick question since it has an expression at the end that you use to figure out for y using x

A 20 ft flag pole casts a shadow 32 ft long. What is the angle of elevation of the sun?

Nookie1986 [14]

Answer:

The angle of elevation of the sun is 32°

Step-by-step explanation:

Right Triangles

The flagpole and the ground form a right angle (90°). In triangles with right angles, the trigonometric ratios are satisfied.

Each acute angle has an adjacent leg and an opposite leg. The tangent ratio relates to both legs.

$\displaystyle \tan x=\frac{\text{opposite leg}}{\text{adjacent leg}}$

The opposite leg to angle x is 20 ft and the adjacent leg is 32 ft, thus:

$\displaystyle \tan x=\frac{20}{32}=0.625$

Calculate x by using the inverse tangent:

$x=\arctan 0.625$

$x=32^\circ$

The angle of elevation of the sun is 32°

How much of the circle is shaded? Write your answer as a fraction in simplest form. 1/3 and 1/7

Ludmilka [50]

Answer:

11/21

Step-by-step explanation:

1/3=7/21

1/7=3/21

(7+3)/21=10/21

21/21-10/21=11/21

Thus 11/21 of the circle is shaded.

A convex polygon has Choose... sides when the interior angle sum is 1980º.

Viefleur [7K]

Answer:

13 sides.

Step-by-step explanation:

(n - 2) = 1980 / 180 = 11.

n = 13

When the sum of the interior angles is 1980 degrees, the convex polygon will have 13 sides.

i hope this helps and is right! p.s. i really need brainliest :)
