Question

Two parallel lines are crossed by a

What is the value of d?

0

d = 55

d = 75

d = 125

d = 155

Answer 1

Option C.

Explanation:

Let as consider parallel lines r and s are cut by transversal q. On line s where it intersects with line q, the uppercase left angle is 125 degrees and the bottom right angle is d degrees.

We need to find the value of d.

If a tranversal line intersect two parallel lines, then the alternate exterior angles are equal.

Uppercase left angle and bottom right angle are alternate exterior angles. So we can say that

d = 125°

Therefore, the correct option is C.

Answer 2

d = 125°

Explanation:

The complete problem is attached.

According to the graph, the value of angle d would be 125°, by vertical angles theorem, which states that two angles that are opposite each other when two lines crosses, they are congruent.

Therefore, the right answer is the third option.
