Question

If a quadrilateral has 3 angles measure 60,45 and 100; find the measure of the fourth angle

Answer 1

155

Explanation:

Answer 2

The fourth angle is 155

Explanation:

The sum of the angles of a quadrilateral are 360 degrees

60 + 45 + 100 + x = 360

Combine like terms

205+x = 360

Subtract 205 from each side

205+x-205 = 360-205

x =155
