Answer:
The perimeter of the shape is of 40.56 units.
Step-by-step explanation:
Perimeter of a shape:
The perimeter of a shape is the sum of the lengths of all its sides.
In this question:
The sides are a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61.
So

The perimeter of the shape is of 40.56 units.
Answer:

Step-by-step explanation:
Given:
Profit in the month of June from first location is 
Profit in the month of June from second location is 
Now, total profit from the two locations can be obtained by adding the profits from each of the two locations.
Now, adding both the profits, we get:

Plug in the given values and simplify. This gives,

Now, we need to combine the like terms using commutative property.
Therefore, rearranging the terms, we get:

Therefore, the correct option is the first option.
Answer:
Option D is correct.
The measure of 
Step-by-step explanation:
is isosceles and
and
are base angles.
Isosceles Triangle:
A triangle with two equal sides, and two congruent base angles that means the angles are equal
By the definition, the base angles are equal i.e, 
Since, YZ bisects
Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles
then,
or
Substitute the value of
;

The sum of measures of these three angles of triangle WXY is equal to the 180 degree.
In triangle WXY we have;

Substitute the value of
and
in above formula:
or
Simplify:

Combine like terms ;
or

Simplify;

Substitute the value of x in
;

Therefore, the measure of
