Question

10. In the adjoining figure, straight lines AB and CD intersect at O. Find x and the measure of ск E (3x + 7) (x + 5)° 40° B (i) ZAOC (ii) ZAOD (iii) ​

Answer 1

Step-by-step explanation:

2x + 10 + 2x + 50 = 180 ( straight line)

4x + 60 = 180

4x = 120

x = 30 degrees.

angle COE = 2x + 10 = 2(30) + 10 = 60+10 = 70 degrees

angle COB = 2x + 10 + 2x = 70 + 2(30) = 70+60 = 130 degrees.

angle AOC = angle BOD = 50 degrees ( vertically opposite angles)

angle AOD = angle COB = 130 degrees ( vertically opposite angles)

hope it helps. :)
