If the measures of three angles in a triangle are (2x+15)º, (10x – 20)º, and (3x + 2)º, then find the value of 15x – 3. I am getting 180. Is it right ?

The sum of all the internal angles of a triangle = 180*
(2x+10)+10x-20)+(3x+2)=180 15x-3=180 15x=183 x=183/15=12.2 x=12.2 (15x-3)=15(12.2)-3=180

I guess you did a mistake? 2x+15
Please can you check it
it's 2x+15!
I got 15x -3 = 180
I wrote wrong here. but I put the correct numbers
yes I got the same
2x + 15 + 10x – 20 + 3x + 2 = 180
x = 12.2 is right!
