Explanation

Solution

• 13 ÷ 2 = 6, remainder 1

• 6 ÷ 2 = 3, remainder 0

• 3 ÷ 2 = 1, remainder 1

• 1 ÷ 2 = 0, remainder 1

Reading the remainders from bottom to top: 1101

So, 13 in binary = 1101.

Explanation

Two angles are called supplementary when their measures add up to 180 degrees.

Two angles are called complementary when their measures add up to 90 degrees.

Explanation

Given proportion:

2 : 7 :: 14 : x

We can set up an equation based on the proportion:

2/7 = 14/x

Cross-multiplying:

2x = 14 × 7

2x = 98

Dividing both sides by 2:

x = 98/2

x = 49

Explanation

The sum of the exterior angles of any polygon is always 360 degrees. 

As for the interior angles, the sum of all the interior angles in a polygon is equal to: (n-2) x 180

Explanation

A pie chart represents data in a circular form, and the sum of all the angles in the chart always equals 360°.

Each slice of the pie chart corresponds to a portion of the total, and their angles add up to 360°.
