Step-by-step explanation:
Answer:
Angle 1, 2, 4 = 45 degrees
Step-by-step explanation:
2x+15 = x+30
-15 both sides
2x = x+15
-x both sides
x = 15
Plug x = 15 into x+30 or 2x+15
15+30 = 45
2(15)+15 = 45
Justify means plug answer in and verify
so distribute 8(3-7x)=24-56x
143=7+24-56x
143=31-56x
minus 31 both sides
112=-56x
divide both sides by -56
-2=x
justify
plug it back
143=7+8(3-7x)
143=7+8(3-7(-2))
143=7+8(3-(-14))
143=7+8(3+14)
143=7+8(17)
143=7+136
143=143
true
x=-2
