Answer:
4. right
5.acute
6. obtuse
Step-by-step explanation:
so it says that you do Pythagorean theorem where a^2+b^2=c^2.
you then multiply each number by itself and if the number on the left is bigger than the one on the right, it's obtuse and its acute if the right is bigger than the left and if they equal its right.
4. 60x60=3600
11x11=121
61x61=3721
3600+121=3721
3721 does equal 3721 so its a right triangle
5.4x4=16
5x5=25
7x7=49
16+25=41
41 does not equal 49
left number is bigger than the right number so its acute
6.25x25=625
19x19=361
7x7= 49
625+361=986
986 does not equal 49
left number is bigger than the right number so it's obtuse
