Question

the four angles of a quadrilateral are 2(x-10) degree ; (x+30) degree;(x+50)degree and 2x degree. find all the four angles​

Answer 1

Answer:

Step-by-step explanation:

2x - 20 + x-30 + x+50 +2x=360

6x +60 =360

6x= 360-60

6x = 300

x = 300/6

x = 50

2x - 20 = 2 (50-10)= 80

x-30 = 80

x+50 = 100

2x = 100.
