Question

Use the image to answer the question.

A quadrilateral is formed by joining four lines. The top left vertex is given as a, the top right vertex is given as b, the bottom right vertex is given as c, and the bottom left vertex is given as d.

Using the given angles, what is the interior angle measure of a?

Answer 1

To determine the measure of interior angle a in the quadrilateral formed by vertices a, b, c, and d, you need to consider the properties of the angles in a quadrilateral.

The sum of the interior angles in any quadrilateral is always 360 degrees. If you have the measures of the other three angles (b, c, and d), you can find angle a by the formula:

\[
\text{angle a} = 360^\circ - (\text{angle b} + \text{angle c} + \text{angle d})
\]

If you provide the values for angles b, c, and d, I can help you calculate the measure of angle a.

Answer 2

a=115,b=120,c=75,d=50
