Question

three angles of a quad are lateral 115°, 50°, 68°, find the fourth angle.​

Answer 1

Answer:

the measure of the fourth angle be x°.

We know that the sum of the angles of a quadrilateral is 360°.

Therefore, 54 + 80 + 115 + x = 360

⇒ 250 + x = 360

⇒ x = (360 - 250) = 110.

Hence, the measure of the fourth angle is 110°.
