Jannette says because 's sides form a Pythagorean triple and 's side lengths are multiples of 's side lengths. Is she correct? Explain your reasoning.
The similar triangles ABC and DEF may or may not have equal lengths
Janette's claim that triangles ABC and DEF are similar triangle is true
How to prove or disprove Janette's claim?Start by calculating the length of the third sides using the Pythagoras theorem.
[tex]a^2 = b^c + c^2[/tex]
For triangle ABC, we have:
[tex]AC^2 = 20^2 + 21^2[/tex]
[tex]AC = 29[/tex]
For triangle DEF, we have:
[tex]58^2 = 40^2 + EF^2[/tex]
This gives
[tex]EF^2 = 58^2 - 40^2[/tex]
[tex]EF = 42[/tex]
So, we have the following corresponding lengths on both triangles
Triangle ABC Triangle DEF Common ratio
20 40 2
21 42 2
29 58 2
Since the common ratios are the same, then the triangles are similar
Hence, Janette's claim is true

The measure of the supplement of an angle is 46 more than 3 times the compliment of the angle. Find the angle.
Answer: 68 degrees
Step-by-step explanation:
Let the measure of the angle be x.
The supplement of the angle is 180 - x as supplementary angles add up to 180 degrees.
The complement of the angle is 90 - x as complementary angles add up to 90 degrees.
We can set up an equation.
180 - x = 46 + 3*(90-x)
180 - x = 46 + 270 - 3x
Combine like terms:
2x = 136
Divide both sides by 2:
x = 68
What are supplementary and complementary angles?
Supplementary angles are angles whose measure adds up to 180°Complementary angles are angles whose measure adds up to 90°
First, let's assign a variable to the unknown angle: xNext, set up an equation that represents the information you were given:
The supplement of an angle (180 - x) is [=] 46 more than 3 times the complement (90-x):
180 - x = 3 (90 - x) +46
Now, solve for x:
180 - x = 3 (90 - x) +46
180 - x = 270 - 3x +46
180 - x = 316 -3x
-x = 136 -3x
2x = 136
x = 68
The angle is 68°

A triangular prism has a base that is a triangle with each side length measuring 6 inches. By how much is the prism’s lateral surface area increased if the base of the triangle is doubled? Please show work because I need to write it down. Also pls reply ASAP, as this is due tomorrow.
Answer:
The lateral surface is increased by a factor of 2.
Step-by-step explanation:
Since each side of the base was doubled in length, but the height of the prism remains the same, all sides double in area.
Therefore the total new lateral area is double what it was.
The lateral surface is increased by a factor of 2.
Find the measure of the missing angles .
Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°

What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 27 ÷ (- 34 - 45)
Now, We can simplify as;
⇒ 27 ÷ (- 34 - 45)
⇒ 27 ÷ - 79

Suppose a radius of a circle is 17 units and a chord is 30 units long. Find the distance from the center of
the circle to the chord.
Answer:
Let A represent the center of the circle. Let the point B be a point at the intersection of the one end of the chord and the edge of the circle. Finally, let C represent a point between the center of the circle and the midpoint of the cord. The triangle ABC is a right triangle with a 90 degree angle at ACB. Since the cord length is 30, the bisected segment BC is length 15 .
(length AB)^2 = (length BC)^2 + (length AC)^2
17^2 = 15^2 + (length AC)^2
289 = 225 + (length AC)^2
add -225 to each side
64 = (length AC)^2
take square root of each side
8 = length AC

A 13 meter long cylinder with a diameter of 6 meters has a square prism with a base length of 3 meters hole going all the way through the center of it as shown in the diagram (not to scale). Find the volume of the composite shape rounding to the nearest cubic meter. Hint: while working the problem carry figures at least three decimal places, then round to the nearest cubic meter only once at the very end.
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

Simplify:
3(2p + 3 + 4p)
Answer:
6p + 9 + 12p
18p + 9
Step-by-step explanation:
3(2p + 3 + 4p)
Multiply all the numbers by the outside number. ex: 3(2p + 9). Multiply 3 x 2 which is 6. then you multiply 3 x 9 which is 27. So the answer would be 6p + 28.
Pt 2. 3 times 2 is 6 so you get 6p. Then you multiply 3 times 3 which is 9. then 3 times 4p which is 6 p.
pt 3. combine the like terms. 6p + 12p equals 18p.
so the answer would be 18p + 9.
