Question

In the given figure , lines AB and CD intersect at O. Find the value of x.
D
B
А
7x/5x
0
C​

Answer 1

Step-by-step explanation:

we know that totalmeasurement of liner angles are 180

7x+5x=180

12x=180

$x = \frac{180}{12}$

$x = 15$

Answer 2

Bro Angle on a straight line is 180°

So, 7x + 5x = 180°

12x = 180°

x = 180°/12

x = 15°

Hence value of x is 15°
