I will assume you are dealing with a triangle    all angles add to 180 degrees

65 + 3x-10 + 2x = 180

5x - 10 = 115

5x=125

x = 25          B = 65    C = 50

If its in traingle the sum of the 3 angles is 180 deg. so just add them and compare the sum to 180.

A+B+C=65+(3x-10)+2x=55+5x=180deg- The sum of degrees in traingle.

pass all the numbers to the right side:

5x=180-55=125   -> x=125/5=25deg

But what do each angles measure and what is X

A +  B + C  = 180   so

65+ (3x - 10) + (2x)  = 180

55 + 5x  =  180     subtract 55 from each side

5x = 125               divide both sides b 5

x  = 25°

So B =  3(25) - 10   =  65°

And C  = 2(25)  = 50°

What each angles measure depends on your problem, we both assumed you are dealing with triangle.

x is just a variable, I guess it dosent mean anything important.

thank you
