Find the value of x in the given figure using properties of parallel lines. A) 138°
B) 48°
C) Can't be determined.
D) 42°

Step-by-step explanation:

Given

The diagram above

Find x

When two parallel lines are divided in such a way as it is in the above figure;

x and 138 are said to be supplementary angles

The rule about supplementary angles is that, they add up to 180

In other words,

To solve this, we subtract 138 from both sides

Hence, the value of x when solved using the properties of parallel lines is:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
