What is the value of k?

AlladinOne [14]

So first, you want to find that top angle Y. You can do this by subracting 115 from 180 giving you 65. Next I started searching for K. After inserting numerous numbers into the equation I found that 10 gave me the answer as shown below.

180 - 115 = 65

4(10) + 5 = 45

6(10) + 10 = 70

70 + 65 + 45 = 180

Add those together and you get 180 degrees, which is always the total number of degrees for a triangle. So your answer is 10.

Hope this helps! <3

<h3>Answer:</h3>

C=52.08π

<h3>Solution:</h3>

Circumference of a circle:
C=2πr
where
π=3.14...
r= radius
In this case, r is equivalent to 26.04 ft.
C=2π×26.04
Multiply:
C=52.08π (in terms of pi)

Hope it helps.

We have a shape that has an area of 112 inches squared. Convert the units to centimeters squared. (HINT: Perform multiple conver

<h3>Answer: 722.5792 square centimeters</h3>

Work Shown:

$112 \text{ in}^2 = 112 \text{ in}^2 \times \frac{2.54 \text{ cm}}{1 \text{ in}} \times \frac{2.54 \text{ cm}}{1 \text{ in}}\\\\112 \text{ in}^2 = (112 \times 2.54 \times 2.54) \text{ cm}^2\\\\112 \text{ in}^2 = 112 \times (2.54)^2 \text{ cm}^2\\\\112 \text{ in}^2 = 722.5792 \text{ cm}^2\\\\$

Notes:

1 inch = 2.54 cm exactly
The conversion factor $\frac{2.54 \text{ cm}}{1 \text{ in}}$ is used to convert from inches to cm. The inches unit in the denominator cancels with one of the inches unit from the original 112 square inches figure.
We use two identical copies of the same conversion factor to convert from square inches to square centimeters. This is the "multple conversion" your teacher is referring to.
Think of "square inches", aka $\text{in}^2$ , as "inches times inches". Or think of a 1 inch by 1 inch square that has an area of 1 square inch. The same applies for the square centimeter unit as well.
