In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the 3rd angle is 68 degrees more than the measure of the 2nd angle. Use the fact that the sum of the measures of the 3 angles of a triangle is 180 degrees to find the measure of each angle. The measure of the smallest angle is??

    Let us assume the scond angle to be x. Then first angle=2x Third angle=x+68 x+2x+x+68=180 Can u find x nw?

    ok so i get 4x+68=180. so now i subtract 68 from both sides?

    then i get 4x=112 so i divide by 4 on both sides and get 28? After that how do i find the measure of the smallest angle?

    The value of x is the measure of small angle.

    so 28 is the measure of the smallest angle?
