Question

find the third angle 1st angle 90 second angle 110 find third​

Answer 1

So, first angle = 50 degree

second angle = 110 degree

third angle = 90 degree

We know, sum of all angles of a quadrilateral is 360 degree

Let the fourth angle be x.

Therefore, 50 + 90 + 110 + x = 360

or, 250 + x = 360

or, x = 360 - 250

or, x = 110

The fourth angle measures 110 degree.
