Question

In the given figure, lines AB and CD intersect at O. Find the value of x.​

Answer 1

Answer:

since AB is a straight line angle form by this line will be 180°

7x+5x=180

12x=180

x=180/12

x=30/2

x=15

7x=7x15=105

5x=5x15=75

Answer 2

Answer:

X = 15

Step-by-step explanation:

As AB is a straight line so 7x + 5x = 180 ( Linear Pair)

So 12x = 180

x = 180 ÷ 12

We get x = 15
