<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:
0.9 L of hardener
Step-by-step explanation:
Find the total mL then convert into L
60*15=900
900mL=0.9
We need to calculate a TIME. Here, TIME = job / rate
Here,
1 JOB 1 1
------------------------------------- = ------------------ = ---------------
JOB/5 min + JOB/15 min 1/5 + 1/15 3/15+1/15
1
= ------------ minutes = 15/4 minutes = 3 3/4 minutes (answer)
4/15
B) 154, 171, 188, 205, 222
A constant value (17) is added to get the next number
