Question

The three angles of a quadrilateral are 65,55 and 130 Find its fourth angle ​

Answer 1

Answer:

65+55+130+x=360

x=360-250

x=110

Answer 2

Answer:-

Given,

the three angles of a quadrilateral are

— 65°, 55°, 130°

Let,

the fourth angle be x

Now We know that,

The sum of all the angles of a quadrilateral is 360°.

So, x + 65° + 55° + 130° = 360°

or, x = 360° – (65° + 55° + 130°)

or, x = 360° – 250°

or, x = 110°

So, the fourth angle is 110°
