A quadrilateral has angles that measure 87°, 69°, and 104°. What is the measure of the fourth angle?

Answers

The answer should be ................... 100
Sum of angles of quadrilateral = 360

87 + 69+ 104 + x = 360

156 + 104 +x = 360

260 + x = 360

thus, x = 100

Thus, the measure of the fourth angle is 100 degrees
