Answer:
0.71
Step-by-step explanation:
1st attempt = 
%
2nd attempt = 
%
To get the average of something, find the sum of the numbers and then divided the sum by the total number of values there are.
⇒ 63 + 79 = 142
⇒ 142 / 2 = 71%
⇒ 71% = .71
In the Pythagorean theorem, a squared minim b squared equals c squared. If you apply that formule to question 2.
17^2-8^2 = 289 - 64 = 225 = 15^2.
Therefore, the answer to first question is yes
Then, for question 2, you do the same thing.
41^2 - 40^2 = 51
Here, 51 is not a square number. Most importantly it is not the square of9,
So this triangle is not right angled
Answer:
c
Step-by-step explanation:
Sum of the interior and exterior angle =180
If we have 5 sides, then we have 5 angles,
so
sum of exterior and interior angles =180*5= 900⁰.
