Answer:
<em>m<A = 40 deg</em>
<em>m<B = 60 deg</em>
<em>m<C = 80 deg</em>
Step-by-step explanation:
2x + 3x + 4x = 180
9x = 180
x = 20
m<A = 2x = 2(20) = 40
m<B = 3x = 3(20) = 60
m<C = 4x = 4(20) = 80
m<A = 40 deg
m<B = 60 deg
m<C = 80 deg
Answer:
cot B = 48/55

Answer:
see below
Step-by-step explanation:
4x-7=13
Add 7 to each side
4x-7+7 = 13+7
4x=20
Divide each side by 4
4x/4 = 20/4
x = 5
