Question

the measure of two adjacent angles of a quadrilateral are 130 degree and 30 degree and the other two angles are equal.find the measure of each of the angle​

Answer 1

two adjacent angle measures 130 and 30 degree.

= let the other two angles of the quadlaterals=x

A/q
= x+x+130+30= 360( sum of angles of the quadrilaterals)
= 2x+160= 360
= 2x= 360-160
= 2x= 200
= x= 200÷2
= x= 100 degree answer!!!

Answer 2

Let other angle be x and y
A/Q
x=y ...........(ⅰ)
Therefore, x+y+130+30=360
x+x=200
2x=200
x=100
From(ⅰ) y=100
