Question

AOB is a straight line. Find the value of x.
(3x-15)
(2x+15)
Find x,​

Answer 1

Answer:

Given

AOC = ( 3X - 15 )

COB = ( 2X + 15)

To find = x =?

Solution =

Since AOB is a straight line and OC intersect at O

Therefore using linear pair angle property

AOC + COB = 180

=> (3X - 15) + ( 2X + 15) = 180

=> 5X - 15 + 15 = 180

=> 5X = 180

=> X = 180/5

=> X = 36

NOW AOC = 3*36 - 15

= 108 - 15

= 93

Again COB = 2*36 + 15

= 72 + 15

= 87
