Answer:

m∆IED= 83°

m∆JFG= 87°

Step by step

m∆IED is 97° so if you subtract 97 from 180(a straight line) you would get 83°

and the same for m∆JFG if you subtract 93 from 180 you get 87°

hope this helps

Pls need help, free brain<br> full answer
Nesterboy [21]

Answer:

Equation : 35 + 6.40t < 86.20

t = less than 8 hours

Step-by-step explanation:

If t equals the number of hours they can rent the room before going over their set limit, we would add the base amount (35) to the hourly (6.40t) less than 86.20.

So :

35 + 6.40t < 86.20

6.40t < 51.20 (subtract 35 on both sides)

t < 8 (divide 6.40 on both sides)

:)
