The angle of elevation of the sun relative to an observer standing at the tip of the shadow is 16.9°.
<h3>What is trigonometry?</h3>
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
Given that:-
- A cell phone tower that is 70 meters tall is built on level ground and casts a shadow 230 meters long at a particular moment.
The angle of elevation will be calculated by applying trigonometric property in the triangle given below;-
= tan(0.3043)
= 16.9
Therefore angle of elevation of the sun relative to an observer standing at the tip of the shadow is 16.9°.

8 times 7
Y = x - 6
x: -5, -8, -7
y: -5 - 6, -8 - 6, -7 - 6
y: -11, -14, -13
x: -5, -8, -7
y: -11, -14, -13
Option B
The sum of the measures of the exterior angles of a 53 - gon is 360 degrees
<em><u>Solution:</u></em>
The formula for sum of exterior angles "n" is:
Distribute 180
Therefore, sum of measure of exterior angles is 360 degrees
<h3>Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360 degrees</h3>
Thus, in a 53 gon, sum of measure of exterior angles is 360 degrees
Answer:
197 million square miles
Step-by-step explanation:
Remark
What the equator is telling you is that the circumference around the earth is approximately 24902 miles. So before you can find the surface area, you need to find the radius of that circumference.
Equations
C = 2*pi*r
Area = 4pi*r^2
Solution
<em><u>Radius</u></em>
C = 24902
pi = 3.14
r = ?
24902 = 2 * pi * r
r = 24902 / (2 * pi)
r = 3965.29
==========
<em><u>Surface Area</u></em>
Area = 4 * pi * r^2
Area = 4 * 3.14 * 3965.29^2
Area = 4 * 3.14 * 15,723,498
Area = 197 000 000 square miles
