Question

The value of "y" in the figure is
•12°
•24°
•36°
•None of the above
Please help me​

Answer 1

Step-by-step explanation:

The angles opposite each other when two lines cross are vertically opposite angles. They are always equal.

In this figure

According to definition

6 - y = 3y - 42

⇒ -y -3y = -42 - 6

⇒ -4y = -48

⇒ y = $\frac{-48}{-4}$

⇒ y = 12     [ negative in denominator and numerator cancel out]

Hence your answer is

a) 12
