If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
Hello,
Center is (2,-11) and radius is 8
You would multiply 6 by 3 and x by 4. You would end up getting 4x = 18 and then you simplify that to get 9/2 or 4.5.
