from a point 12 ft from the base of a building, the angle of elevation from the ground to the top of the building is 70 degrees. Which is the closest to the height of the building
Answers
Answer:
c 33ft .....
Step-by-step explanation:
c is correct
The possible height of the building is 33 ft.
What is Angle of Elevation?
The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
Here, Let the height of the building be x ft
Base = 12ft.
Angle of Elevation = 70⁰
Now, tan α = perp. / base
tan 70⁰ = x/12
2.74 = x/12
x = 12 X 2.75
x = 33
Thus, the possible height of the building is 33 ft.

Please help! A robotic vacuum cleaners can clean 2 square feet of carpet in 8 minutes. About how long does it take for it to clean a carpet covering a room with the dimensions shown below?
Answers
Answer: 6480
Step-by-step explanation: So since the dimensions are easy to calculate, just multiply 9 by 4 and 15 by 3, then you get 36 and 45. Multiply 36 by 45 and you get 1620, but since the vacuum can get 2 square ft, then divide by 2 and you get 810. Since it takes 8 minutes to clean up, multiply 810 by 8 and you get 6480. I do believe

Hello There!
The shown angles have a sum of 90 degrees
This is noticeable because there is a square at the vertex which indicates that its a right angle
A right angle has a measure of 90 degrees
That being said we can create an equation to solve for x
90 = 66 + 8x having made an equation we now solve for x
step 1 subtract 66 from each side
90 - 66 = 24
66 - 66 cancels out
now we have
24 = 8x
step 2 divide each side by 8
8x/8=x
24/8=3
we're left with x = 3
Answer:
x=3
Step-by-step explanation:
8x+66=90 complement
8x=90-66
x=24/8=3

What are the dimensions of the rectangle?
OA) 12 by 7
B) 18 by 5
C) 15 by 4
D) 16 by 3
help
Answers
Answer:
Step-by-step explanation:
Width = w units
Length = ( w + 13 ) units
Perimeter of rectangle = 38 units
2* (length + width) = 38
2*(w +13 + w )= 38 {Use distributive property: a*(b+c)=(a*b) +(a*c)
2* ( 2w + 13) = 38
2*2w + 2*13 = 38
4w + 26 = 38 {Subtract 26 from both sides}
4w = 38 - 26
4w = 12 {Divide both sides by 4}
w = 12/4
w = 3 units
Length = 3 + 13 = 16 units
