. In the diagram at the right, you are given m∠ =100 , m∠ =40 , m∠ = m∠5 = 110 . Find the measures of the other labeled angles.

If the picture were bigger and the angle numbers were all shown, I could help.

I can open the image and enlarge it, but the big problem is that you did not supply angle numbers with their measures, except for #5.

Hi Seul,

use the sum of interior angles of polygon formula.

(n-2)*180

In this question, we have a pentagon so substitute n=5 and that would give you the sum of all 5 angles. If one of the angles is unknown, you can find the measure by subtracting the sum of other 4 angles.

as for the other angles outside the pentagon, called as exterior angles - you can use supplementary angles to find their measures.
