Question

HELP!! ⚠️ In the diagram below, the two vertical segments are parallel. What is the total number of degrees in angles a, b, c, d?

Answer 1

360°

Explanation:

According to the properties of parallel lines, the following deductions can be made:

<a and <c are exterior angles of same side, therefore they are supplementary.

Thus,

m<a + m<c = 180°

<b and <d, are alternate interior angles, therefore, they are supplementary.

Thus, m<b + m<d = 180°.

The total numbers of degrees of a, b, c, d will all sum up to give 360°.
