5x-10=80 x=16

B=2(16) - 10 = 22

C= 3(16)+20 = 68

I'm not sure if thats right or not.

I will assume that by "measurement A=70" you are referring to angle A

then 70 + 2x-10 + 3x+20 = 180

5x = 100

x = 20

then angle B = 30 and

angle C = 80

knowing that in any triangle, the largest side is opposite the largest angle, the largest side must be opposite angle C, which would be AB
