The answer will be “b” because exponent means mutiply
It might be -0.35, -0.3, 0.5, and 0.55
First, ask somebody else like your teacher, also use your brain
Pythagorean theorem: a²+b²=c²
Where c = length of the hypotenuse (diagonal of a triangle)
60²+40²=c²
3600+1600=c²
5200=c²
c=√5200
c ≈ 72.11 ft
