Answer:
Tan.
Step-by-step explanation:
First way;
Tan (90-θ )=Cot θ Tan (90+θ )= -Cot θ
1st explanation, QUOTATIONS!
"tan90∘ is undefined because you can't divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined."
2nd explanation, QUOTATIONS!
"That's undefined because as you approach 90° from either direction, tan approaches positive or negative infinity. cot(90°) hence approaches 1/infinity (either positive or negative) which is just 0."

Answer:
i dont know
Step-by-step explanation:
Step-by-step explanation:
angle(A+B+C)=180°{sum of angle of triangle}
C=180°-135°
C=45°
now,
sin theta=p/h
sin 45°=10/AC
1/√2=10/AC
AC=10√2
Ac=14.14

The formula for the perimeter, P, of a rectangle is P = 2(l + w), where l represents the length and w represents the width.
A. Todd has a string that is 26 inches long and wants to create a 9-inch-long rectangle with it. Substitute these values into the formula above, and solve for w to determine how wide Todd’s rectangle must be. Show your work.
B. Todd solved for the width arithmetically, as follows:
The length of the rectangle is 9 inches, so the sum of the lengths of the two long sides is 2 • 9 = 18 inches.
The string is 26 inches long, and 18 inches are used for the long sides of the rectangle, so the number of inches available for the short sides is 26 − 18 = 8 inches.
A rectangle has 2 congruent short sides, so the length of each short side, or the width of the rectangle, is 8 ÷ 2 = 4 inches.
Describe how Todd’s arithmetic solution process is similar to your algebraic solution process from part A, and how they are different.
C. The perimeter formula can be solved for w, in terms of P and l, as shown below.
P = 2(l + w)
P = 2l + 2w
P − 2l = 2w
= w
Explain why it could be useful to solve the perimeter equation for w in terms of P and l.
Answer:
p= 2L + 2w
p= 2×26 + 2×9
35-52=18
w=35
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
Answer:
10 feet
Step-by-step explanation:
Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?
The rug is shaped as a rectangle
The formula for the Perimeter of a rectangle = 2L + 2W
Perimeter = 36 feet
Length = 8 feet
Hence
36 = 2(8) + 2W
36 = 16 + 2W
2W = 36 - 16
2W = 20
W = 20/2
W = 10 feet
Therefore, the Width of the rug is 10 feet
Find the surface area off the prism. Please help me solve this!
volume of a pyramid with a square base of length 5m is 75m³. Find it's hieght
Answer:
The height of the pyramid is 3 m.
Step-by-step explanation:
Given;
volume of pyramid, V = 75 m³
length of the square, L = 5 m
The volume of a pyramid is given as;
V = area of the square base x height
V = Ah
where;
A = L² = 5 x 5 = 25 m²
h = V/A
h = (75) / (25)
h = 3 m
Therefore, the height of the pyramid is 3 m.
$600 at 4% for 9 months.
The simple interest for the principal amount of $600 at the rate of 4% for 9 months will be equal to $216.
What is Simple interest?A quick and simple way to figure out interest on that money is to use the simple interest approach, which adds interest at the same rate for each daily cycle, and it is to the initial principal amount. A way to figure out how much interest will be charged on an amount of money at a specific rate and for a specific duration of time is by using simple interest.
As per the given information in the question,
Principle amount, P = $600
Time, T = 9 months
Rate, R = 4%
SI = (600 × 9 × 4)/100
SI = $216.
The SI will be $216.

2 • xy (midsegment) = sum of the bases
Plug in the numbers
2 • 12.5 = 3x + 1 + 15
Add 1 and 15 together
25 = 3x + 16
Subtract 16 on both sides and you should get:
9 = 3x
Divide both sides by 3
9/3 = 3x/3

Write three different expressions in any form equivalent to each given expressions below.
Answer:
3^-3 for the first answer. The second answer is 3^7.
Step-by-step explanation:
If you multiply two numbers with the same base and exponents, the exponents are added up.
If you divide two numbers with the same base and exponents, the numerator would subtract the denominator.
So the answer to the first question is 3^-3. The second answer would be 3^7.

How old is Linn
Answer:
3
Step-by-step explanation:
Where did you get this question?
The number of cookies left, if Matt has 5 Cookies and Linn eats 3 of the cookies, is 2.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
The total number of cookies, t = 5,
The number of cookies Linn eats, n = 3,
Calculate the number of cookies left by using subtraction as shown below,
The number of left cookies = Total number of cookies - The number of cookies Linn eats
The number of left cookies = t - n
The number of left cookies = 5 - 3
The number of left cookies = 2
Thus, the number of cookies left is 2.

We have,
A chord is a line segment connecting two points on a circle.
A chord is different from a diameter, which is a chord that passes through the center of the circle.
The chords in a circle are all the same with the same length.
From the given diagram,
There are two chords.
This can be written as:
(15 + 8) = 23 makes one chord.
(10 + x) makes one chord.
Now,
23 = 10 + x
Solve for x.
23 = 10 + x
23 - 10 = x
x = 13
Thus,
The value of x in the circle is 13.
