How to find area of parallelogram with coordinates of verticles?

ExtremeBDS [4]

You find a parallelogram area by this formula:
$A=b\cdot h$
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
$A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\ \\ 
d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b$

And h is the perpendicular distance between both bases.

There are three consecutive even integers. If twice the first integer added to the second is 268,244, find all three integers.

r-ruslan [8.4K]

Answer:

89414,89416,89418

Step-by-step explanation:

Let n bet the positive integer and then 2n is an even integer because multiplying n with 2 makes it an even integer.

Now, 2n+2, 2n+4 are the next integers.

Therefore, three consecutive integers are: 2n, 2n+2, 2n+4.

It is given that twice the first integer added to the second is 268,244 that means:

$2(2n)+(2n+2)=268244$

$4n+2n+2=268244$

$6n=268242$

$n=44707$

Therefore, three consecutive integers are:

2n=89414, 2n+2=89416, 2n+4=89418

What are the angle measures of triangle ABC?

Schach [20]

The angle measures of triangle ABC is ∠A=90°, ∠B= 60°, ∠C = 30°. Thus, the correct option is B.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

As it is known that the angles of the triangle are 30°, 60°, and 90°. Therefore, the largest angle is 90° which will be the opposite of the largest side of the triangle, therefore, the measure of ∠A=90°.

Also, the shortest angle of the triangle is 30°, which will lie at the opposite of the smallest side of the triangle, therefore, the measurement of the ∠C=30°.

Now, the angle left is ∠B therefore, the measure of ∠B=60°.

Hence, the angle measures of triangle ABC is ∠A=90°, ∠B= 60°, ∠C = 30°. Thus, the correct option is B.

Myerson borrowed $8,500 at 9% ordinary interest for 200 days. After 120 days, he made a partial payment of $4,000. What is the f

Lady_Fox [76]

Interest due at the end of 120 days
= 8500(120/365)(.09) = 251.51

so of his $4000 payment, $3748.49 will go towards reducing the debt.
so balance owing = 8500 - 3748.49
= 4751.51

interest for the remaining 80 days
= 4751.51(.09)(80/365) =93.73

total owing at the end = 4751.51+93.73
= $4845.23
