what's the angle of elevation from the bench to the top of this building?​

Answers

If 120 ft is the height of the building,
tan(40deg) = height of building/ perpendicular distance from base of tree to building = 120/x
—> x= 120/tan(40deg)
Distance from bench to building = [120/tan(40deg)]- 50 (calculate this) ——(1)
tan(angle of elevation) = height of building/ distance from bench to building = 120/(answer from (1))
angle of elevation = arctan( 120/answer from (1) ) (calculate this too)

Find The Area Of This Figure Round Your Answer To The Nearest Hundredth Use 3.14 To Approximate Pi

Answers

Answer:

105.12 ft²

Step-by-step explanation:

Area of the figure = area of the rectangle + area of half a circle

= L*W + ½(πr²)

Where,

L = 10 ft

W = 8 ft

r = ½ of 8 = 4 ft

π = 3.14

Plug in the values

Area = 10*8 + ½(3.14*4²*)

Area = 80 + 25.12

Area = 105.12 ft²

Jackson is 5 years old. His brother Micah is 20 years older than him. Which equation represents Micah's age in comparison with Jackson's age?

Answers

Answer:

M=5+20

Step-by-step explanation:

I’m using M for representing Micah’s age.

This would represent Micah’s age because it says that Micah is 20 years older than Jackson, who is 5. Therefore, you would just need to add 5 and 20 together. Micah is 25 years old.
