Since the exponent is on the outside of the paranthesis, you'd have to multiply it by everything on the inside: a^m x b^m
Use Pythagorean Theorem
c2 = a2 + b2
152 = a2 + 12
a2 = 152 - 122
=225 - 144 = 81
a = 9 ft
Distance from base of antenna = 9ft
The delivery route took 4 hours and 15 minutes.
Because 9:50 + 4 hours is 1:50
1:50 + 15 minutes is 2:05
Hope this helps! Have a great rest of your day :)
