Answer:
Option C
Step-by-step explanation:
ΔABC and ΔDEF are similar triangles.
By the property of similar triangles, corresponding sides of the similar triangle are proportional.
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
[tex]\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}[/tex]
[tex]\frac{6}{DE}=\frac{6}{3}[/tex]
DE = 3
Perimeter of ΔDEF = Sum of measures of the sides of the triangle
= DE + EF + DF
= 3 + 3 + 5
= 11
Therefore, Option C will be the correct option.

A running track has two semi-circular ends with radius 25m and two straights of length 87.6m as shown.
Calculate the total distance around the track rounded to 1 DP.
Answers
The total distance around the track is 332.2 meters
How to calculate the total distance?The complete question is in the attached image
The given parameters are:
Radius, r = 25 m
Length, l = 87.6 m
Start by calculating the circumference of the two semi-circular ends using:
[tex]C = 2\pi r[/tex]
So, we have:
C = 2* 3.14 * 25
Evaluate
C = 157
The total distance around the track is then calculated as:
Total = 2l + C
This gives
Total = 2 * 87.6 + 157
Evaluate
Total = 332.2
Hence, the total distance around the track is 332.2 meters

Step-by-step explanation:
The measure of an inscribed angle is 1/2 the measure of the intercepted arc.
∠X is an inscribed angle and arc QRS is its intercepted arc.
arc QRC has a measure of 122 + 76 = 198
Therefore, m∠X = 1/2(198) = 96
So, 19x + 1 = 96

Answers
Answer:
C. 80 square centimeters
Step-by-step explanation:
Edge 2021
The lateral surface area of the given square pyramid is 80 cm².
What is lateral surface area?The lateral surface of an object is its entirety, excluding its base and top (when they exist).
Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.
Given that, a square pyramid has side lengths each measuring 8 centimeters.
The height of the pyramid is 3 centimeters.
The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]
= 2×8√[(8²/4) + 3²]
= 16√[(64/4) + 9]
= 16√[16 + 9]
= 16×5
= 80 cm²
Therefore, the lateral area of the pyramid is 80 cm².

-6x/-6 = -9/-6
x= 3/2
Hope this helps :)
Answer:
The value of x in this equation is 3/2.
Step-by-step explanation:
First, let's take the original equation:
2 + 5x - 2x = 6x + 3x - 7
In order to solve for x, we must isolate the variable x on one side of the equation, and the rest of the numbers on the other side of the equation. So we take: 2 + 5x - 2x = 6x + 3x - 7 and use some of the properties of equality:
We start with 2 + 5x - 2x = 6x + 3x - 7 and see that we can minus 2 on both sides of the equation as highlighted below:
2 + 5x - 2x = 6x + 3x - 7
2 + 5x - 2x - 2 = 6x + 3x - 7 - 2
This simplifies the equation to 5x - 2x = 6x + 3x - 9.
Remember, we can arrange the equation like this along as we do on one side what we do on the other. Now, we have 5x - 2x = 6x + 3x - 9, and see that the rest of 6x and 3x needs to go on the left side of the equation. In order to do this, we can minus 6x from both sides of the equation as shown below:
5x - 2x = 6x + 3x - 9
5x - 2x - 6x = 6x + 3x - 9 - 6x
which then simplifies to 5x - 2x - 6x = 3x - 9. Now we can do the same thing by minus 3x from both sides of the equation.
5x - 2x - 6x = 3x - 9
5x - 2x - 6x - 3x = 3x - 9 - 3x
5x - 2x - 6x - 3x = -9
Now, we must simplify the left side of this equation by adding together the variable numbers 5x - 2x - 6x - 3x. This is shown below:
5x - 2x - 6x - 3x = -9
3x - 6x - 3x = -9
-6x = -9
Lastly, we can divide the number -9 by -6 to get the answer of what 1 x equals. This means -9/-6 = 3/2.
X is indeed equal to 3/2
In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Answers
Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.

∠A and \angle B∠B are vertical angles. If m\angle A=(2x+26)^{\circ}∠A=(2x+26) ∘ and m\angle B=(3x+21)^{\circ}∠B=(3x+21) ∘ , then find the measure of \angle B∠B.
Answers
Answer:
36degrees
Step-by-step explanation:
If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)
Given the following
m<A = (2x+26)°
m<B = (3x+21)°
Equating both expressions
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
Get the measure of m<B
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21
m<B = 36degrees
Hence the measure of angle B is 36degrees
what does 2(3y – 4) =
Answers
Let's use the distributive property to simplify this problem.
The first thing we want to do is change the minus to plus a negative.
Now distribute or multiply the 2 by each of the terms inside the parentheses.
So we get 2(3y) + 2(-4) and this simplifies to 6y + -8
Note that if you wrote your answer as 6y - 8, it means the same thing.
