Question

The angles of a quadrilateral are x 0

, (x – 10)0

(x + 30)0 and 2x0

. Find all the angles​

Answer 1

Answer:

68 degrees, 58 degrees, 98 degrees, 136 degrees

Step-by-step explanation:

x+(x-10)+(x+30)+2x=360 (sum of all angles of a quadrilateral=360 degrees)

=5x+20=360

=5x=360-20

=5x=340

=x=340/5

=x=68

(x-10)=68-10= 58

(x+30)=68+30= 98

2x=68x2= 136

To verify add all of the found values and see whether they add up to 360.
