Answer:
Right angles are congruent
Step-by-step explanation:
One right angle can be transformed to another using rigid transformations such as translation ,rotation and reflection.This is basically the definition of congruence because the idea is to transform one object to another.
It would be 7/8 because there is 7 filled in out of 8 ANDWER: 7/8
Answer:
Step-by-step explanation:
Alright, lets get started.
Area is given as 49 square inches.
The formula for area A = 
base is given as x
Height is given as x
Hence area is A
A = 
Multiplying 2 in both sides

Taking square root on both sides

hence the answer is x = 9.9 in : Answer
Hope it will help :)
10.5 or 10 1/2 basically ten and a half
Answer:
Option A - Permutation; number of ways = 210
Step-by-step explanation:
Given : At a competition with 7 runners, medals are awarded for first, second, and third places. Each of the 3 medals is different.
To find : How many ways are there to award the medals?
Solution :
There are 7 runners but medals are three.
The first runner up got first medal as one is locked.
The second runner up got second medal as second is locked.
The third runner up got the third medal.
So, There is a permutation.
Number of ways to award the medals is 
We know, 
Substitute the values,



Therefore, Option A is correct.
Permutation; number of ways = 210
