Answers
The measure of angle ∠1 will be 68 degrees.
The missing graph is given below.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The diagram is given below.
Then the measure of angle ∠1 will be
68° + 44° + ∠1 = 180°
∠1 = 68°
The measure of angle ∠1 will be 68 degrees.

Answers
Answer:
Not similar
Step-by-step explanation:
If you have scratch paper, its best to label the angles and sides given. You can also rotate the orientation of one of the triangles if that helps visually.
First lets look at the sides.
Notice the common factor between side AB and side XY.
14/7=2
Notice the common factor between side AC and side XZ.
22/11=2
So far so good right? Well, IF these triangles are similar, that means that angle X must correspond to angle A. Since corresponding angles of similar triangles are equal to each other, lets check of angle X is equal to angle A.
Angle X = 29 degrees
Angle A = 28 degrees
28 does not equal 29 degrees. Therefore, the triangles are not similar. If angles X and A were equal, than the triangles would have been similar due to the Side-Angle-Side rule (SAS).

The time in seconds, t, it takes for a specific object being dropped from a particular height in feet above sea level, h, to reach the ground can be found by the radical function t equals one fourth times radical h period At what height should you drop an object in order for it to reach the ground in 16 seconds?
Answers
Answer:
B.) 4,096 feet
Step-by-step explanation:
You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".
t = (1/4)√x <--- Original equation
16 = (1/4)√x <--- Plug 16 in "t"
64 = √x <--- Divide both sides by (1/4)
4,096 ft = x <--- Square both sides
The object reach the ground in 16 seconds, you should drop it from a height of 4096 feet.
The equation is t=1/4 √x , where t is time in seconds and x is height in feet. To determine the height x at which an object should be dropped to reach the ground in 16 seconds, you can plug in the value of t=16 into the equation:
16 = 1/4 √x
Simplify the equation by multiplying both sides by 4:
4⋅16= √x
64= √x
Now, square both sides to isolate x:
64²=x
4096 = x
Therefore, to have the object reach the ground in 16 seconds, you should drop it from a height of 4096 feet.

Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, we have that the parameters are given as follows:
A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.
Hence the time in years is found as follows:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]13000 = 10000\left(1 + \frac{0.04}{12}\right)^{12t}[/tex]

General Sherman, a tree located in Sequoia National Park, stands 275 feet tall. To see the top of the tree,
Carlos looks up at a 19° angle of elevation. If Carlos is 6 feet tall, how far is he from the base of the tree to the
nearest foot?
Answers
By using trigonometric relations, we will see that the distance between Carlos and the tree is:
D = 781.23 ft
How far is Carlos for the base of the tree?We can model this with a right triangle. We know that Carlos is 6ft tall, and the height of the tree is 275ft.
Then one of the cathetus of the triangle is equal to:
275ft - 6ft = 269ft.
That cathetus is the opposite cathetus to the angle of 19° (the elevation angle). And the adjacent cathetus is the distance between Carlos and the tree.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
a = 19°opposite cathetus = 269ftadjacent cathetus = D.Replacing that, we get:
tan(19°) = 269ft/D
Solving for D, we get:
D = 269ft/tan(19°) = 781.2ft
So we conclude that Carlos is at 781.23 ft of the tree.

How to find the probability?
We will assume that all the beads have the same probability of being randomly selected.
Then the probability of picking a black bead is equal to the quotient between the number of black beads and the total number of beads.
Originally, there are 4 black ones and 3 red ones ( a total of 7).
We want to get the probability of getting a black one given that in the first draw we got a black one.
If in the first draw we got a black one, then now there are 3 blacks and 3 reds (a total of 6 beads).
