Question

The angles of quadrilateral are (5)⁰, (3 + 10 )⁰, (6 − 20)⁰ and ( + 25)⁰


Find i) the value of and

ii) the measure of each angle of the quadrilateral.​

Answer 1

Step-by-step explanation:

sum of all angle of a quadrilateral are 360°

(5)°+(3+10)°+(6-20)°+(+25)°=360°

8x+6x+x+10-20+25=360

14x+x-10+25=360

15x+15=360

15x=360-15

15x=345

x=345/15=23
