Answer:
In order to understand better this problem, we can use the<u> figure attached</u>, in which we have a<u> right triangle</u> (with a 90 degree angle), where is its hypotenuse, is the adjacent side to the angle of elevation from the boat to the top of the lighthouse and is the opposite side to .
Knowing this, we will use the tangent trigonometric function to find :
(1)
(2)
(3)
(4)
Finally:
Answer:
The mean would be 11
Step-by-step explanation:
I don’t know exactly what your asking but x = 3
<u>Area of Banner is 4 sq.ft.</u>
<u>Step-by-step explanation:</u>
Class made 20 smaller rectangles
dimension of each rectangle = 3/5 ft × 1/3 ft
Area f banner = 20 * ( area of 1 rectangle)
⇒ 20 * ( 3/5 * 1/3 )
⇒ 20 * 0.2
⇒ 4 sq.ft
<u>Area of Banner is 4 sq.ft.</u>
