Well if its a 8ft ladder and its being set 2ft off from the base i think the chimney is 6 ft tall cause 8-2 is 6...
The chimney measures approximately 7.75 feet tall.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
To find the height of the chimney, you can use the formula for the length of the hypotenuse of a right triangle, which is:
c² = a² + b²
Where c is the length of the hypotenuse (in this case, the length of the ladder), a is the length of one of the legs (in this case, the distance the ladder is set from the base of the chimney), and b is the length of the other leg (in this case, the height of the chimney).
Plugging in the values given in the question, we get:
8² = 2² + b²
64 = 4 + b²
b² = 64 - 4
b² = 60
b = √60
b = 7.745 ≈ 7.75
Thus, the height of the chimney is approximately 7.75 feet.

Parallel lines r and s are cut by two transversals, parallel lines t and u. Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of u and r, 13, 14, 15, 16. Which angles are corresponding angles with angle 8?
Answer:
s and r
Step-by-step explanation:
The required angle is the corresponding angle of angle 8 which are ∠4, ∠12, and ∠16.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
Parallel lines r and s are cut by two transversals, parallel lines t and u.
And 16 angles are formed
Now,
The angle formed by r and t, = 1, 2, 3, 4
The angle formed by s and t, = 5, 6, 7, 8
The angle formed by s and u, = 9, 10, 11, 12
The angle formed by r and,u = 13, 14, 15, 16
Thus, the required angle is the corresponding angle of angle 8 which are ∠4, ∠12, and ∠16.

The measure of angle JKL in the triangle JKL is 54°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
From the given figure line segments JM and ML are of equal measure as the line segment KM bisects JL and hence bisects the vertex angle.
Therefore,
2x + 5 = 3x - 6.
2x - 3x = - 6 - 5.
- x = - 11.
x = 11.
Now, m∠JKL = 2m∠JKM = 2m∠LKM.
So, m∠JKL = 2[2(11) + 5]°.
= 2(22 + 5)°.
= 2(27)°.

Annie is buying new school supplies. She has a budget of $45, and she has already spent $21. She wants to spend the remaining money on notebooks that cost $4 each. What is the greatest number of notebooks, x, Annie can purchase while staying within her budget?
Part A: Write an inequality to represent the situation.
Part B: Solve the inequality. Show all of your work.
Part C: Interpret the solution in terms of the problem.
Answer:
Part A) 45-21 ≥ 4x
Part C) She could buy up to 8 notebooks
Step-by-step explanation:
She already spent $21 so you would need to subtract that from the total budget. The sign would be greater than or equal to since that's the max amount.
45-21 ≥ 34
34≥4x
Divide both sides by 4 to cancel it out. You would get 8.5 but since you can't buy half a notebook it would be 8.

1.Lin and her brother each created a scale drawing of their backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Whose drawing is larger?
2.How many times larger is Lin's drawing than her brother's drawing? You are being asked to compare the size of the areas of the drawings.
Answer:Part 1) The scale for the drawings without units are 1/12 and 1/36
Part 2) The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36. The explanation in the procedure
Step-by-step explanation:we know that
1) Lin used a scale of
Remember that
1 ft=12 in
substitute in the scale
That means ----> 1 unit in the drawing represent 12 units in the actual
2) Her brother used a scale of
Remember that
1 yd=36 in
substitute in the scale
That means ----> 1 unit in the drawing represent 36 units in the actual
therefore
The scale for the drawings without units are 1/12 and 1/36
Part 2) Whose drawing is larger?
The scale drawing 1/12 is larger than the scale drawing of 1/36
To find out how many times as large is the scale 1/12 than the scale of 1/36
Divide 1/12 by 1/36
The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36
Explanation
Let supposing that we want to represent in the drawing a measure that in its real size measures 36 units.
In the scale of 1/12, the drawing will show a measure of 3 units (remember 3(12)=36 units).
At the 1/36 scale, the drawing will show a measurement of 1 unit (remember 1(36)=36 units).
Therefore the largest drawing will be with a scale of 1/12.

HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!
Answer:
Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%
Answer:
A 4% difference
Step-by-step explanation:
Convert 4 feet 2 into 4.16666666
4/4.16666666= 0.96 or 96%
4 feet was 96% of 4 feet 2 in
100 - 96= 4%
And this shows that there was a 4% error.
