Answer 1

Finding the Angles of a Trapezoid

To find the angles of a trapezoid, we need to know the ratio between the lengths of its bases. In this case, the ratio is given as 1:2, meaning that the longer base is twice the length of the shorter base.

Let's denote the shorter base as a and the longer base as 2a.

To find the angles, we can use the following formula:

Angle = 180 - (360 / n)

Where n is the number of sides of the trapezoid.

A trapezoid has four sides, so n = 4.

Now, let's calculate the angles:

1. Angle at the shorter base: - 180 - (360 / 4) = 180 - 90 = 90 degrees.

2. Angle at the longer base: - 180 - (360 / 4) = 180 - 90 = 90 degrees.

3. Angles at the non-parallel sides: - Since the non-parallel sides are not specified, we cannot determine their exact angles without additional information.

Therefore, the angles of the trapezoid with bases in a 1:2 ratio are as follows: - Angle at the shorter base: 90 degrees. - Angle at the longer base: 90 degrees. - Angles at the non-parallel sides: Cannot be determined without additional information.

Please note that the angles provided are based on the given ratio of the trapezoid's bases. If you have any additional information or specific measurements, please let me know, and I'll be happy to assist you further.
