How do you solve question 27 and 28
Brrunno [24]

Answer:#1 C.30 #2 40


Step-by-step explanation:

3x+15=7x-5

3x+15+5=7x-5+5

3x+20=7x

3x-3x+20=7x-3x

20=4x

20/4=4/4x

5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30

So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180

4x-48+3x+4=180

7x-44=180

7x=224

x=32

2(32)-24

64-24=40
