Suppose that in a certain triangle, the degree measures of the interior angles are in the ratio $2: 3: 4$.

if the largest interior angle measures $x^\circ$, what is the value of $x$?

x = 80°

Step-by-step explanation:

Let the measures of each angle be 2y, 3y, and 4y. Then

2y + 3y + 4y = 180

               9y = 180

                 y =  20°

Then, the measure of the largest angle is

4y = 80°

 x = 80°

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
