Question

find the measure of angle y in the given figure ​

Answer 1

Answer:

in quadrilateral sum of all angles is equal to

360 degrees

=>85+100+95+y=360degrees

=>280+y=360 degrees

=> y=360-280

=> y=80 degrees

Answer 2

Given,

Three angles of a quadrilateral 100°,85°, and 95°,

To Find,

The value of y.

Solution,

Using the angle sum property of the quadrilateral which states that" The sum of angles of a quadrilateral measure 360°."

So, the sum of angles of quadrilateral will be

100+85+95+y = 360
280+y = 360

y = 360-280

y = 80°

Hence, the value of y is 80°.
