Question

x = 1 = Hence, the four angles are 110°, World ॥ 1. Find the missing angle of the following q How 360 45° - 2x - 5 80° 105°​

Answer 1

Answer:

Step-by-step explanation:

The sum of all four angles of the quadrilateral is 360°. To find the fourth angle or the missing angle in a quadrilateral when the measurements of three angles of a quadrilateral are known, then subtract the three angles from 360° to calculate the missing angle.

Let the measure of the fourth angle be x°.

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