Question

What is the measure of ? Four-sided figure divided into four triangles. Triangle on top has angles labeled two, forty-one degrees, and one hundred twelve degrees. Triangle on right has angles labeled forty-four degrees, sixty-six degrees, and three. Triangle on the bottom has angles labeled twenty-nine degrees, four, and one hundred nine degrees. Triangle on the left has angles labeled forty-three degrees, one, and sixty-nine degrees.

Answer 1

There are 4 triangles, all in all.
The total interior angle is 180.

180 = 69 + 43 + (1)
(1) = 180 - 69 - 43
(1) = 68

180 = 112 + 41 + (2)
(2) = 180 - 112 - 41
(2) = 27

180 = 66 + 44 + (3)
(3) = 180 - 66 - 44
(3) = 70

180 = 109 + 29 - (4)
(4) = 180 - 109 - 29
(4) = 72
