Question

In the figure line L parallel || line m and line n is the transversal, if angle ABC = a° and angle BFG=50°, then the value of a is ?

A) 50°
B) 40°
C) 150°
D) 130°

please choose the correct option ​

Answer 1

Answer:

D) 130 degrees

Step-by-step explanation:

Hey , the answer to this question is D) 130 degrees.

Here is the explanation

if we take , angle DBF = a ( they are vertically opposite angles and we know that vertically opposite angles are equal ).

We know that angle DBF + 50 degree = 180 ( the lines l and m are given parallel and if the lines are parallel then the interior angles on the same side of the transversal are supplementary which means that there sum is 180 degrees ).

So , By doing the appropriate calculations ,

angle DBF = 180-50 degree

I.e. angle DBF = 130 degrees is the answer.

Hope you understand :)
