What is the perimeter, to the nearest inch, of the kite?
Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.

The Fitzgerald paid $3,200 to heat their home in the year of 2018. By the end of the year 2019, they saw the cost of heating their home rose to $3,516 for the year. What could be use to find the difference in what they paid from 2918-2019?
Answer:
Substraction
Step-by-step explanation:
Given that
The amount paid in the year 2018 is $3,200
And, in the year 2019 the amount paid is $3,516'
We need to find the differnece between two years so how we can find
Basically we need to subtract the amount i.e.
= $3,516 - $3,200
= $316
hence, the difference is of $316 from 2018 to 2019

what is the vaule of x I REALLY NEED HELP
Answer:
x = 69
Step-by-step explanation:
angles in a triangle add up to equal 180
which means that, x + x + x - 27 = 180
x + x + x = 3x
3x - 27 = 180
* add 27 to both sides *
-27 + 27 cancels out
180 + 27 = 207
207 = 3x
* divide both sides by 3 *
3x / 3 = x
207 / 3 = 69
we're left with x = 69

To wash her car, Amy used 25 ? of water
A)millilters
B)liters
Answer:
Liters
Step-by-step explanation:
a Mili(thousandth)liter is a small unit of volume. Liters( a thousand milliliters) is the base unit of volume and larger, so it's B.
The requried to wash her car, Amy used 25 liters of water. Option B is correct.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
Here,
The question doesn't specify what unit of measurement the 25 refers to, so it's unclear whether the answer should be in milliliters or liters. However, assuming that the unit of measurement is liters, the answer would be:
Amy used 25 liters of water to wash her car.
If the unit of measurement is milliliters, the answer would be:
Amy used 25,000 milliliters of water to wash her car.
Note that 1 liter is equal to 1000 milliliters, so 25 liters is equal to 25,000 milliliters.
Thus, the requried To wash her car, Amy used 25 liters of water. Option B is correct.

Answer:
a) 5 cm
b) 8 cm

Step-by-step explanation:
It can be worthwhile to work the last attachment (a) first, since these are all variations of the same triangle.
The Pythagorean theorem tells you the sum of the squares of the legs is the square of the hypotenuse.

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 14,16,27
Answer:
this triangle is "obtuse
Step-by-step explanation:
Since sides 14 and 16 add up to 30, which is more than the third side, 27, we DO have a triangle here. The sides of lengths 14 and 16 form an angle greater than 90 degrees, and so this triangle is "obtuse." It's not a right triangle either, because the Pythagorean Theorem is not satisfied: 14^2 + 16^2 = 452, which is NOT 27^2.

Solution :
A. None
None of the identical triangles provided in the sketch can be composed into a rectangle, it can be formed into a square. A rectangle is a quadrilateral with four sides having opposite side equal in length. The two adjacent sides of a rectangle are different in size. Thus a rectangle cannot be a square.

Jenna's dogs used 999 chew toys last year. The animal shelter used 2,277 277 chew toys. How many times as many chew toys did the animal shelter use? How to do
Answer: 2.28 times
Step-by-step explanation:
When finding out the number of times more that the animal shelter used chew toys than Jenna's dogs, you need to divide the number used by the animal shelter by Jenna:
= Number used by animal shelter / Number used by Jenna's dogs
= 2,277 / 999
= 2.28 times
Notice that if you multiply Jenna's dogs 999 toys by 2.28 you will get approximately 2,277.
