5n + 3 + 4n = 30 combine the like terms on the left

9n + 3 = 30 Subtract 3 from both sides

9n = 30 - 3

9n = 27 Divide by 9

n = 27/9

n = 3

Answer:

AC is the longest side

AB is the shortest side

Step-by-step explanation:

We can find the third angle

A+B+C = 180

55+80+C = 180

135+C = 180

C = 180-135

C =45

The longest side is opposite the largest angle

B is the largest angle so AC is the longest side

C is the the smallest angle so AB is the shortest side
