Which equations could be used to solve for the unknown lengths of △ABC? Check all that apply.

GuDViN [60]

Applying the trigonometric ratios, the equations that can be used are:

sin 45 = BC/9

cos 45 = BC/9

<h3>How to Apply the Trigonometric Ratio?</h3>

In the given image below, to find the unknown lengths of the triangle, we would apply the following trigonometric ratios:

To find AC, use the cosine ratio, CAH.

To find BC, use the sine ratio, SOH.

sin 45 = opp/hyp = BC/9

sin 45 = BC/9

cos 45 = adj/hyp = BC/9

cos 45 = BC/9

One angle of a rhombus is 108 degrees and the shorter diagonal is 9 inches long. How long is the side of the rhombus

valkas [14]

Now, for a rhombus, all sides are the same length, and the diagonals bisect the vertex they cut, so they cut them in halves, and they also meet at right-angles, and cut each other in halves as well

that means, if the angle is 108, the shorter diagonal will cut that in two equal angles, of 54 each, check the picture below

and since they each other cut in halves where they meet, one side of the shorter diagonal will then be half of 9, or 9/2 or 4.5

since the angle is in degrees, make sure your calculator is in Degree mode

Lisa's store collects 5% sales tax on every item sold if if she caused if she collected $22. In sales tax what was the cost of t

Advocard [28]

Im assuming the question is asking: if she collected $22 in sales tax what was the cost of the items her store sold. you should make sure you type the question correctly otherwise it'll be hard to answer.

going with my assumption of what the question is, we want to find the total cost of all items her story sold. let that cost be c. since there is 5% sales tax on everything and we know the sales tax is worth $22,m we have:

5%(c) = 22
dividing both sides by 5% (or .05) gives:
c = $440

Does 2 1/3-1 3/4 need require renaming

ANEK [815]

Answer:

$\frac{7}{12}$

Step-by-step explanation:

$2 \frac{1}{3} - 1 \frac{3}{4}$

The fractions above are known as mixed numbers (that is, fractions that contain the combination of a whole number and proper fraction). The mixed numbers can equally be renamed as improper fractions. However, renaming can only occur the the mixed numbers are being transformed as below:

$\frac{7}{3} - \frac{7}{4}$

The transformation occur through a simple approach thus: for the first mixed number; 2 1/3 = 2 multiplied by 3 plus 1 divide by 3 equals 7/3. Similarly, mixed number 1 3/4 is transformed by this: 1 multiplied by 4 plus 3 divide by 4 equals 7/4.

Simplifying further to arrive at final result implies,

$\frac{7}{3} - \frac{7}{4}$
