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
