(3x-5)+(x+1)=180
x=46
3(46)-5=133
m
This is the answer i got 147
The answer would be C because the first figure is half of every number on the second figure making it similar it’s not congruent because there not the same size
B subtract 18 from both sides
Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
x = 10
m<A </span><span>= 8x +12
</span>m<A = 8(10) +12
m<A = 80 + 12
m<A = 92
answer
m<A = 92
