Question

two lines AB and CD intersect each other at a point o such that angle AOC :angle AOD =5:7. find all the angles .​

Answer 1

Answer:

Hope it helps u

let angle AOD=7x and angle AOC=5x

angle AOC+angle AOD=180 (L. P)

5x+7x=180

12x=180

x=180/12

x=15

angle AOC=5x=5*15=75

angle AOD=7x=7*15=105

angle COB=angle AOD=105. (V. O)

angle DOB=angle AOC=75. (V. O)
