Answer:
C
Step-by-step explanation:
if you divide the two numbers by 4 you have:
16/4=4
20/4=5
(if you divide or multiply both of the numbers with the same number, the ratio will remain the same)
So the two numbers are same
Answer:
<em>Choice B. 16 feet.</em>
<em>The height of the tree is 16 ft</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Similar triangles have their corresponding side lengths proportional by a fixed scale factor.
We are given the drawings of a tree and a wall and it's assumed both triangles are similar. We need to find the scale factor and find the height of the tree.
Comparing the corresponding distances from the viewer to the base of the tree and the base of the wall, we can calculate the scale factor as 24/6=4.
Applying the same factor to the height of the model, we get the height of the tree is 4*4 = 16 ft.
Choice B. 16 feet
The height of the tree is 16 ft
Answer:
(D)250 ft
Step-by-step explanation:
Circumference of Circle O
For a circle of diameter d, Circumference =
Therefore:
The approximate length of the diameter, d is 250 ft.
The correct option is D.
Answer:
17 no for side c
take 37 degree as reference angle
using sine rule
sin 37 =p/h
0.60=6/c
0.60c=6
c=6/0.c0
c=10
for side d
using pythagors theorem
H^2=P^2+B^2
(10)^2=(6)^2+B^2
100=36+B^2
100-36=B^2
64=B^2
=B
8=B
Step-by-step explanation:
1) In this question, we are going to make use of the formula for the area of that sector, to find the central angle.
2) So, let's write it out an expression involving the area of a circle, the unshaded area, and the shaded one and then plug into that the given data:
Thus, the centra angle of that shaded area is 72º
