If the three angles of a triangle measure 3x, 4x and 5x, respectively, what is the measure of the largest angle in the triangle?
Sum of interior angles of a triangle = 180 3x+4x+5x=180 Solve for x. Plug in the value of x in 5x and find the largest angle. Does that help? @lookitswill
oh ok. I did try and add 3x 4x 5x together but i didn't know what to do with the x value.
