The hypotenuse-leg theorem states that two right right triangles are congruent if the hypotenuse and a leg of one triangle are congruent to the hypotenuse and a leg of the other triangle. Looking at the given options,
For a,
We only know that two legs are congruent. We can't confirm that the hypotenuses are congruent
For b,
two legs and two hypotenuses are congruent
For c, the triangles don't have hypotenuses because they are not right triangles.
For d, the hypotenuses of both triangles is the common line. This means that they are congruent. Two legs are also congruent.
Thus, the correct options are
b. Yes
d. Yes

Alexa read a total of 54 books over 9 months. If Alexa has read 120 books so far, how many months has she been with her book club? Assume the relationship is directly proportional.
Answers
If the relation between the book read by Alexa and the number of months she takes to read them is directly proportional, then, if x is the number of months she took to read 120 books, you can write:
[tex]\frac{x}{120}=\frac{9}{54}[/tex]By solving for x and simplifying, you obtain:
[tex]\begin{gathered} x=\frac{9}{54}\cdot120 \\ x=20 \end{gathered}[/tex]Hence, Alexa read 120 books in 20 months

Answers
The Solution.
In 1966, which is the initial year(t); t = 0, and minimum wage(y), y = $1.25
Similarly.
In 2015, t = 49 years , (that is, 1966 to 2015), and y = $8.75
The rate of growth to the nearest percent is

Answer:
Corey stepped 59.71 ft away
Explanation:
The situation is sketched in the following diagram.
The distance from the foot of the tree is y and x for angles 41 and 68 degrees respectively.
Therefore, the distance Corey has to step away is y - x.
Now, from trigonometry, we know that
[tex]\tan (68^o)=\frac{\text{opposite}}{\text{adjacent}}[/tex][tex]\Rightarrow\tan (68^o)=\frac{\text{8}0}{\text{x}}[/tex]We solve for x and get
[tex]\begin{gathered} \Rightarrow x\tan (68^o)=80 \\ \Rightarrow x=\frac{80}{\tan (68^o)} \end{gathered}[/tex]since tan (68) = 2.475.., the above becomes
[tex]x=\frac{80}{2.75\ldots}=32.32[/tex]Now, for angle 41 we have
[tex]\tan (41^o)=\frac{opposite}{\text{adjacent}}[/tex][tex]\tan (41^o)=\frac{80}{y}[/tex]solving for y gives
[tex]y=\frac{80}{\tan (41^o)}[/tex]since tan(41) = 0.869..., the above becomes
[tex]y=\frac{80}{0.869\ldots}[/tex][tex]\Rightarrow y=92.0295\ldots[/tex]Therefore, the distance Corey has to step away from the tree to get a better view is (rounded to the nearest hundredth)
[tex]y-x=92.0295-32.322[/tex][tex]\boxed{y-x=59.71.}[/tex]Use the point highlighted in the graph below to write the equation in point slope form for the line provided.

Making the equation of the graph using the Point-Slope Form:

[tex]\text{ m = }\frac{y_2-y_1}{x_2-x_1_{}}[/tex]From the graph, we have one set of coordinates given: (2, 3)
However, we cannot solve the slope with one point alone, thus let's find another point that's along the line and easier to find. From the graph, we get (0,4).
Let's now compute for the slope (m).
[tex](x_1,y_1)=(0,4);(x_{2,}y_2)=(2,3)_{}[/tex][tex]\text{ m = }\frac{3\text{ - 4}}{2\text{ - 0}}\text{ = }\frac{-1}{2}[/tex]Let's now make the equation using the Point-Slope Form using (2,3) as (x1,y2),

By the concept of parallels lines the value of x is 4 .
What are parallels lines?Coplanar, straight lines that don't intersect anywhere are considered parallel lines in geometry. Lines in the same three-dimensional space that never cross one another and are said to be parallel. Curves that are parallel to each other and maintain a setting a minimum distance do not touch or intersect. Lines in a plane that consistently have the same separation are said to be parallel. Nothing can cross a parallel line. Lines that cross at a straight angle of 90 degrees are called perpendicular lines. Two lines in the same plane that are equally spaced apart and never cross each other are referred to in geometry as parallel lines. Both vertical and horizontal can be used. Parallel line examples abound in daily life, such as the rows of notebooks and zebra crossings.

Answers
Since the polygon has seven angles we deduce it is a heptagon. In that case the sum of the interior angles must be equal to 900°. We can formulate the following equation accordingly.
120°+(4*x-3)°+ (x+14)°+ 45°+ 135°+ (x-31)°+ (x*6+20)° = 900°
120°- 3° +14° + 45° + 135° - 31° + 20 + 4x + x + x + 6x = 900° (Organizing)
300 ° + 12x = 900° (Operating like terms)
12x= 900° - 300° (Transposing 300° to the other side of the equation)
12x= 600° (Subtracting 300° from 900°)
12/12x= 600° / 12 (Dividing by 12 on both sides of the equation)
x= 50°
Answer is: x= 50°

using (0, 2 ) , then

C = 2
f(x) = 2[tex]a^{x}[/tex]
