Answer:
AB= 36 degrees
Step-by-step explanation: AB + BC + AC = 96
but AB = AC [isosceles triangle]
2AB + 24 = 96
2AB = 96 - 24 = 72
AB = 72/2 = 36
AB = 36 degrees.
Answer:
5/8.
Step-by-step explanation:
a^-1 = 1/a
So here we have:
(8/5)^-1
= 1/ (8/5)= 5/8.
The answer is 660 miles in 15 minutes
you would have to multiply 44 by 15
44 x 15
=660
