Answer:
as a semicircle, a hexagon, and a rectangle
Step-by-step explanation:
The first attachment shows the decomposition according to the answer choice above. It would make area computation about as simple as it could be.
__
The second attachment shows a decomposition with a circle. It leaves a very odd shape in the middle that is not easily divided into triangles, rectangles, or trapezoids.
The third attachment shows a semicircle, a pentagon, and two triangles. The pentagon is <em>not a regular pentagon</em>, so might require further decomposition in order to determine its area.
Answer:
100cm
Step-by-step explanation:
AC = 40
BC = 40 (definition of congruent)
AB = 1/2(40) = 20
40+40+20 = 100
<u>Given</u>:
Given that PQR is a triangle.
The measures of the sides of the triangle are 4,5 and 6.
We need to determine the measure of ∠Q.
<u>Measure of ∠Q:</u>
The measure of ∠Q can be determined using the law of cosines formula.
Thus, we have;
Substituting p = 6, q = 4, r = 5, we get;
Simplifying, we get;
Dividing, we get;
Thus, the measure of ∠Q is 41°
Hence, Option b is the correct answer.
The area of the square is 9 square inches.
The area of the circle is about 7.065. As a result, the area of the shading region is 1.94 square inches. Hope it help!
