A= equilateral triangle

B= right triangle

C= obtuse triangle

Step-by-step explanation:

For the first box, B would be incorrect, since an equilateral triangle's angle measurements would all be equal. 62+62 is 124, and a triangle needs to add up to 180. As the final angle is 56, it can't be equilateral!

For the second box, C is the incorrect answer, since it is both a right triangle and scalene. The first angle is 22, the second is 90, and the third is unknown. As it needs to add up to 180, it wouldn't be possible for the unknown angle to be 158.

For the third box, C is also incorrect, since it needs to add up to 180. 108+72+72 is not possible, since that would be much higher than the 180 total.  

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
