Answer:
Option A. Triangle STR
Step-by-step explanation:
we know that
If two triangles are congruent, then the corresponding sides and the corresponding angles are congruent
In this problem
If the two triangles of the figure are congruent
then
the corresponding sides are
MN and RS
NO and ST
MO and RT
and the corresponding angles are
∠N≅∠S
∠O≅∠T
∠M≅∠R
therefore
NOM≅STR
Answer:
1 34
2 45
3 23
Step-by-step explanation:
We first calculate the area of the entire pool and the side walk.
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
True or false it will be true
Answer:
5√3 or
8.66 to the nearest hundred.
Step-by-step explanation:
Length of each line of the triangle = 30/3 = 10.
The altitude, side and 1/2 base make a right triangle.
So by Pythagoras:
10^2 = 5^2 + h^2 where h = altitude.
h^2 = 100 - 25 = 75
h = √75 = 5√3.
