<span>No, it doesn't. To find out if it's a right angled triangle, we use Pythagorean triple. It states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the opposite and adjacent sides. Obviously, the longest side, which is our hypotenuse is 24. So we want to find out whether the square of our hypotenuse is equal to the sum of the squares of the other two sides i. e 13 and 21.
24^ 2 = 576 ; 13^2 = 169 ; 21^2 = 441;
So is 576 = 169 + 441. An emphatic No: hence the triangle isn't right angled since it doesn't satisfy pythagorean triple.. A^2 is not equal to B^2 + C^2 where a is the hypotenuse and b and c the opposite and adjacent sides.</span>
Answer:
the answer is -7 I have to subtract the last to numbers
Answer:
6.5
Step-by-step explanation:
when a negative is multiplied by a negative it in turns turns into a positive...hence 2+4.5
We need to write the given statement in math terms:
y increased by 4
Recall that increased means that we are adding 4 to the previous number.
Then the mathematical expression is:
y + 4
The quantity y has been increased by 4 units.
