Does 2.1,7.2,7.5 make a right triangle

2.1 , 7.2 , 7.5 does NOT make a right triangle

Step-by-step explanation:

acute    

obtuse    

right angled  

c is the hypotenuse

a and b are the adjacent and the opposite

the values given are 2.1  , 7.2  , 7.5

hence :

c would be 2.1

a would be 7.2

b would be 7.5

now we can put this into the right angled triangle formula to see if its correct.

lets first see the value of

= 7.2^2  +  7.5^2

= 108.09

to check if its a right angled triangle we check if the value of c^2 gives 108.09.

find the value of

= 2.1 ^2

=4.41

hence 4.41 is NOT equal to 108.09

hence its not a right angled triangle but rather an acute angle.

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

yes because they have the same amount of green and blur marbles.
