Question

Calculates the size of the angle α \alpha

α40

Video Solution

Solution Steps

00:00 Find angle A
00:04 Lines are parallel according to the given
00:11 Alternate angles are equal between parallel lines
00:16 And this is the solution to the question

Step-by-Step Solution

Let's review the definition of alternate angles between parallel lines:

Alternate angles are angles located on two different sides of the line that intersects two parallels, and that are also not at the same level with respect to the parallel they are adjacent to. Alternate angles have the same value as each other.

Therefore:

α=40 \alpha=40

Answer

40 40
