Answer:
The measure of each angle is 143 degrees.
Step-by-step explanation:
We are given the following in the question:
A nonagon in which measure of seven angles are:
138, 154, 145, 132, 128, 147, 130.
Angle sum property of a nonagon:
- The sum of interior angles if a nonagon are 1260 degrees.
Let the two equal angle of nonagon be x degrees. Thus, we can write:
Thus, the measure of two equal angles is 143 degrees.
I will just write the answers in order of the boxes from left-to-right and then up-to-down, so here I go...

Answer:
Decompose the figure into two semicircles and one rectangle and add the areas.
Step-by-step explanation:
A composite shape is a given shape that comprises more than a plane figure. The total area is determined by addition of separate areas of figures making up the composite figure.
When two semicircles are included on the two sides of a rectangle, a composite figure is formed. To determine its area, calculate the individual areas of each semicircle and rectangle, then add the values.
Therefore, decompose the figure into two semicircles and one rectangle and add the areas is the accurate answer.
