Answer:

The correct answer is  option C

They are complementary angles

Step-by-step explanation:

From the figure we can see two angles <ABC and <LMN,

<u>To find the correct option</u>

m<ABC = 20°° and m<LMN = 70°

m<ABC + m<LMN = 20 + 70 = 90°

<h2>A = 0.625</h2>

There are 8 points between 1 and 0 so divide 1 by 8.

1 / 8 = 0.125

Each point has a value of 0.125.

You can minus 0.125 from 1 until you reach A.

Or you can multiple 0.125 by the number of points from 0 to A, including A.

1 - 0.125 - 0.125 - 0.125 = 0.625

0.125 * 5 = 0.625

<h2>A = 0.625</h2>
