Answer: 5mn + 5m + 4n + 4

2mn - 7mn = 5mn

5m = 5m
stays the same

4n = 4n
stays the same

2 + 2 = 4

if you put them toghether than you get:

5mn + 5m + 4n + 4

sesenic [268]

Answer:

30°, 30° and 120°

Step-by-step explanation:

Using the information given in the question.

let x be the measure of each congruent base angle , then

the third angle = 3x + 30

Sum the 3 angles and equate to 180

3x + 30 + x + x = 180, that is

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Thus

The 2 congruent bas angles are each = 30°

The third angle = 3x + 30 = 3(30) + 30 = 90 + 30 = 120°
