Well I think yo need to determine which angle is the largest, smallest and middle. 

use angle sum of a triangle 

A + B + C = 180 

so 

8x -2 + 2x - 8 + 94 - 4x = 180 

this simplifies to 

6x +84 = 180 

now solve for x. 

substitute back into each angle to find there measure and then rank them smallest to largest 

then use the diagram to get the sides

|dw:1416089424056:dw|

use the 2 letters of the side opposite the angle... and apply to the angle ranking. 

longest side is opposite the largest angle
shortest side opposite the smallest angle. 

hope it helps

i still don't understand.... :(

anonymous · Answer

x=16 and then i don't understand what you mean to do the rest

campbell_st · Answer

ok... so solve the equation for x... as the 1st step

6x + 84 = 180

what is the value of x

anonymous · Answer

16

campbell_st · Answer

ok... so angle A = 8*16 - 2 = 126   angle B = 2*16 - 8 = 24 angle C = 94 - 4*16 

then 

|dw:1416089732900:dw|

so rank the angles 

A
B
C

what sides are opposite

???

campbell_st · Answer

oops reverse the order for shortest to longest 

Angle            Side opposite
 B = 24       
 C = 30
A= 126

anonymous · Answer

so it would be AB,AC,BC???
