labwork [276]

Given:

Five and one half of 2 and one third.

To find:

The number for the given statement.

Is it possible to draw a triangle whose angles measure 50°, 50°, and 80°?

Firdavs [7]

First of all, we know a quality of all interior angles of a triangle, they should add to 180 degrees.

Does 50+50+80 degrees give 180 degrees?

100+80=180 degrees

Therefore, yes, it is possible to draw a triangle with the angle measures given to be 50, 50 and 80 degrees.

Hope I helped :)
