Step-by-step explanation:
In the given picture, it is shown that the triangles have two congruent sides, and one congruent angle between them. The congruent sides are shown by the lines on the sides. The congruent angle is shown by the box outlining the angle (technically a box outlining the angle demonstrates that the angle is a right angle, either way, it proves the congruency).

Answer:
The answer to the question is 540°
Step-by-step explanation:
The reason to the answer is:-
There is a formula which is (n - 2) × 180
n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3
Therefore, 3 × 180 = 540°

A steep mountain is inclined 74 degree to the horizontal and rises 3400 ft above the surrounding plain. A cable car is to be installed from a point 970 ft from the base to the top of the mountain. Find the shortest length of cable needed.
Answer:
3917m
Step-by-step explanation:
We are given that
[tex]\theta=74^{\circ}[/tex]
[tex]h=3400 ft[/tex]
We have to find the shortest length of cable needed.
Let Base=x
We know that
[tex]tan\theta=\frac{Perpendicular\;side}{Base}[/tex]
Using the formula
[tex]tan74^{\circ}=\frac{3400}{x}[/tex]
[tex]x=\frac{3400}{tan74}=975m[/tex]
[tex]y=x+970=975+970=1945m[/tex]
Now, the length of cable needed
=[tex]\sqrt{(3400)^2+(1945)^2}[/tex]
=3917m
Hence, the shortest length of cable needed=3917m
How is solving for the length different from solving for the length of the hypotenuse?

The Mattress Depot paid $400 for a bed wholesale, then marked up the price to sell in the store. The retail price is 450% of the wholesale price. At the end of the season, the store will discount the retail price. Which statements are true? Select all that apply.
a. The retail price of the bed in stores is $1800.
b. If the store discounts the retail price of the bed by 30%, the discounted price is $540.
c. If the store discounts the retail price of the bed by 50%, it will make a profit of 125%.
d. The retail price of the bed is $1400 more than the wholesale price.
e. If the store discounts the retail price of the bed by 20%, it will not make a profit.
Answer:
400*4.5=1600+200=1800
1800-400=1400
d. The retail price of the bed is 1400 more that the wholesale price.

show how you did it
Answer:
answer to top question: x = 3/17
answer to bottom question: x = -1
Step-by-step explanation:
distribute first
5 + 4x - 6 + 8x = -5x + 2
combine like terms
-1 + 12x = -5x + 2
12x = -5x + 3
17x = 3
x = 3/17
5 - 4x + 6 + 8x = -5x + 2
4x + 11 = -5x + 2
9x + 11 = 2
9x = -9
x = -1

Addison and Bert are in the same reading group at school. The book they're reading right now is 256 pages long. Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book. Bert has read 142 pages, and he plans to read 11 pages every day. How many days will it be until Addison and Bert have each read the same number of pages in total? How many pages will they each have read?
Answer: The answer in this photo thanks for a little quiz
The number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.
What is an equation?In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.
Given that, the book they're reading right now is 256 pages long.
Let the number of days be x.
Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.
102+16x -------(i)
Bert has read 142 pages, and he plans to read 11 pages every day.
142+11x -------(ii)
Addison and Bert have each read the same number of pages in total.
So, (i)=(ii)
102+16x=142+11x
16x-11x=142-102
5x=40
x=8
Hence, the number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.

Calculate the value of the sample variance. Round your answer to one decimal place. 9_5,9_5,2,9_5
Answer:
[tex]s^2 = 0.01[/tex]
Step-by-step explanation:
Given
Values: 9/5, 9/5, 2, 9/5
Required
Calculate the sample variance
Sample variance is calculated using:
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex]
First, we calculate the mean
[tex]\overline x = \frac{\sum x}{n}[/tex]
[tex]\overline x = \frac{9/5 + 9/5 + 2 + 9/5}{4}[/tex]
[tex]\overline x = \frac{7.4}{4}[/tex]
[tex]\overline x = 1.85[/tex]
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex] becomes
[tex]s^2 = \frac{(9/5 - 1.85)^2+(9/5 - 1.85)^2+(2 - 1.85)^2+(9/5 - 1.85)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{(-0.05)^2+(-0.05)^2+(0.15)^2+(-0.05)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{0.0025+0.0025+0.0225+0.0025}{3}[/tex]
[tex]s^2 = \frac{0.03}{3}[/tex]
[tex]s^2 = 0.01[/tex]
Hence, the variance is 0.01

an easy way is to solve what is in the parenthesis then multiply by the outside number
but if you need to use the distributive property:
