Answer:
B) 161.5 in²
Step-by-step explanation:
We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.
So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.
Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.
Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).
Multiply: <em>19*8.5</em> = 161.5 in²
Answer:
You can find the midpoint of a line segment given 2 endpoints, (x1, y1) and (x2, y2). Add each x-coordinate and divide by 2 to find x of the midpoint. Add each y-coordinate and divide by 2 to find y of the midpoint. It's important to note that a midpoint is the middle point on a line segment.
In order to see the midpoint formula in use, let's look at an example.
Question:
Determine the midpoint of the line segment with the given endpoints.
A(3, 7), B(9, 1)A(3,7),B(9,1)
Solution:
We can use the formula for midpoint to determine the midpoint: M= (x1 + x2/2 , y1+y2/2)
First, plug the x and y value into the formula:
M=(3+9/2 , 7+1/2)
,
Then, we can calculate the midpoint:
(6, 4)
If you multiply 4 by 4 tenths, the answer is 1.6
tenth = 0.1
four tenths = 0.4
4(0.4) = 1.6
