9² + 12² = 15²

15² = 225

18² = 324

Obtuse Triangle

Step-by-step explanation:

The answers to number 1 for each triangle are solved exactly how they are written :).

The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.

Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.

Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.

Hope it helps!

...........

Answer:

41%

Step-by-step explanation:

All of those percentages need to add up to 100

8 + 8 + 13 + 13 + 25 + 33 = 100

Ok...so now that we made sure they all add up to 100, all you need to do is combine the percentage of students sleeping and doing Homework, to get the full percentage for both.

Homework = 8%

Sleeping = 33%

8 + 33 = 41

So the percent of time a student spends and doing homework is 41%.

Hope this helped!
