I NEED HELP QUICK I WILL GIVE BRAINLEST IF THE ANSWERS ARE RIGHT I NEED ALL THE QUESIONS ANSWERED DO NOT I REPEAT DO NOT COMMENT ON MY QUESTION IF YOU DON'T KNOW THE ANSWER OR IF YOU JUST WANT THE POINTS I WILL REPORT YOU IF YOU DO THAT ONLY I REPEAT ONLY COMMENT IF YOU KNOW THE ANSWERS

1) 150 meters (a squared + b squared = c squared so you would do 90 times 90 + 120 + 120 and then square root that to get 150)
2) 18.02 (a squared + b squared = c squared)
3) 150 (you have to find out the length which is 20 then you do 15*20 and divide that by 2 to get 150)
4) 14.21 (a squared + b squared = c squared)
5) A (8 squared + 15 squared DOES EQUAL 17 squared)
