Correct answer:
"<span>If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle"
the Pythagorean theorem states that in a right triangle, the sum of the squares of the shortest sides is equal to the square of the largest side, the hypotenuse. 
Also, 
If we have a triangle with side lengths a, b and c, where a and b are the shortest, and "a squared plus b squared = c squared" then the triangle is a right triangle.

We know that the perimeter of a cylinder is 2πr we will find it as we do always. The perimeter will be :
2 pi r 
= 2 pi * 20
= 40 pi 
Because it says rounded to the nearest tenth the answer will be : 125.6 cm^3 
Because we have a half of a cylinder we will just divide the answer we got by 2:
125.6cm^3 /2 =62.8
The answer is 62.8 cm^3
        
             
        
        
        
Answer:
70 + 5 + 8/10 + 6/100 + 4/1000
Or
7*10 + 5*1 + 8*1/10 + 6*1/100 + 4*1/1000

Answer:
<2 and <8 
<3 and <5
Step-by-step explanation:
The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .
