Question

If the three angles of a quadrilateral are 65 degree, 110 degree and 85 degree, then its fourth angle is:

a)80∘

b)90∘

c)110°

d)100∘​

Answer 1

Answer:

⇒ x = (360 - 250) = 110. Hence, the measure of the fourth angle is 110°. 2. The three angles of the quadrilateral are 90°, 105°, 85°.

Answer 2

Answer:

Step-by-step explanation:

⇒ x = (360 - 250) = 110. Hence, the measure of the fourth angle is 110°. 2. The three angles of the quadrilateral are 90°, 105°, 85°.
