Answer:
36 yards
Step-by-step explanation:
The triangle is a 3-4-5 right triangle with a scaling factor of 12. No complicated Pythagorean theorem has to be used in this case.
60/12 = 5
48/12 = 4
3 is the only base number remaining.
3(12) =36
Factor square root of 32: 2^5/2.
Factor 4: 2^2
Cancel 2 1/2= 2 1/2.
2 1/2= square root of 2.
