Answer:
Yes it will be greater, he is moving back 3 feet so what you are doing is taking the leg (a2) and multiplying it by 3. Once you do, you see triangle 1 has double and so did triangle 2. Triangle 1 was originally 5.6 (rounded to 6) than went up to 26.1. Triangle 2 was originally 24 and went up to 74.7 (or 75)
Step-by-step explanation:
Triangle 1 (when multiply by 3)
a2+b2=c2
7(square to 2)+b2=27(square to 2)
49+b2=729
-49 -49
--------------------
b2=680
(square root it)
b=26.1 Rounded to nearest tenth
Triangle 2:
a2+b2=c2
7(square to 2)+b2=75(square to 2)
49+b2=5625
-49 -49
-------------------
b2=5576
(square root it)
b=74.7 (or 75 rounded to nearest tenth)
Hope this helps anyone who needs it :)
