Since each square will have an area of 4 cm^2 because they are congruent, then let’s find the side length of them.
Square root of 4 is two
Each side is 2 cm. Since the unshaded triangle has 3 on the base and height, then it is same to assume that the triangle has a base of 6 cm (2 * 3) and a height of 6 cm.
The formula of the area of a triangle is:
1/2 ( base times height)
Let’s plug in some values
1/2(6 * 6)
Multiply
1/2 (36)
Divide
18
Since the triangles are also congruent, then the shaded side has the same area.
The shaded triangle has an area of 8 cm ^2
In order to get an 81 average,
the student has to get 81x5=405
71+96+90+73+?=405
330+?=405
405-330=75
he needs to get an 75
14.08 that’s if in this case “of” means multiply hope this helps
Answer:
or
Step-by-step explanation:
Given
Points:
A(-3,2) and B(-2,3)
Required
Determine the radius of the circle
First, we have to determine the center of the circle;
Since the circle has its center on the x axis; the coordinates of the center is;
Next is to determine the value of x through the formula of radius;
Considering the given points
Substitute values for in the above formula
We have:
Evaluate the brackets
Eva;uate all squares
Take square of both sides
Evaluate the brackets
Collect Like Terms
Divide both sides by 2
This implies the the center of the circle is
Substitute 0 for x
Substitute 0 for x and y in any of the radius formula
Considering that we used x1 and y1;
In this case we have that;
Substitute -3 for x1 and 2 for y1
