Answer 1

Step-by-step explanation:

we all know that sum of interior angles of quadrilateral is 360 degrees.

now the given equation is:

4x,(5x+20),(6x+8),(7x+2).

so what we gave to do is equal the given equation with 360.

we get, 4x+5x+20+6x+8+7x+2=360

22 X+30=360

22 X=360-30

=330

X=330/22

(X=15)

so, 4x= 4x15 =60

5x+20=75+20=95

6x+8=90+8=98

7x+2=105+2=107.

so,add these angles 60+95+98+107=360

so,the required angles for quadrilateral are 60,95,98,107.
