Question

5
The angles of a triangle are (2x +30), (3x - 110)° and (x + 20
Find the val
In the given figure, side BC of AABC is extended to D.


please solve it ​

Answer 1

the angles are (2x + 30), (3x - 110), (x + 20)

2x + 30 + 3x - 110 + x + 20 = 180 (angle sum property)

6x - 60 = 180

6x = 180 + 60 = 240

x = 240/6 = 40

2x + 30 = 80 + 30 = 110

3x - 110 = 120 -110 = 10

x + 20 = 40 +20 = 60
