Without going too much into the proofs angle ACD is congruent to angle DBA.
If ACD is ~= DBA then
ACD = 54 degrees
Explanation:
The figure is a reflection. While orientation isnt preserved in reflections side lengths and angle measures are.
This means that both triangles have the same side length measures and have the same angle measures.
You are given the angle measures of one of the triangles. We also know both triangles are congruent since they both fit perfectly inscribed in the circle.
With this in mind you can prove that all the angles of each triangle are congruent.
Thus
ACD = 54 degrees

Answer:
Step-by-step explanation:
a. These triangles are proportional. Identify the corresponding sides for all three sides.
40 AB------30 YZ
50 AC-------37.5 XY
60 BC---------45 XZ
b. Set up fractions with your corresponding sides to show proportionality. Make sure to show your work for all three side pairs demonstrating that the fractions are proportional.
Fraction: 3/4
40 x3/4 = 30
50 x 3/4 = 37.5
60 x 3/4 = 45
c. Are the triangles similar? If so explain why. If not, explain why not. Your work from Part A & B may help with this.
The triangles are similar
The Side-Side-Side Similarity Theorem states: “If all three corresponding sides of two triangles are proportional, then the triangles are similar".
Answer:
A. Sides AB, BC, and CA are proportional to YZ, ZX, and XY, respectively.
B. 3/4(AB) = YZ, 3/4(BC) = ZX, 3/4(CA) = XY
3/4 x 40 = 30 3/4 x 60 = 45 3/4 x 50 = 37.5
C. Yes, by SSS
Step-by-step explanation:
a. and b. are self-explanatory, but I will explain c.
When testing if two triangles are similar, they have to have the same except for scaling and flipping or turning. You know triangles are the same if all three sides are equal (SSS), two angles are equal (AA), or if there are two equal sides with an equal angle between them (SAS).
Since similar tringles can be scaled, these rules turn into if all three sides are proportional (SSS), two angles are equal (AA), or if there are two proportional sides with an equal angle between them (SAS).
These two triangles have proportional sides, so SSS applies and they are similar.

In degrees what is the measure of MFE
There's a lot going on in this problem, but I think I know how to solve it. So let's first address the fact that opposite angles are equal.
Let's also address the fact that (x + 6) + (3x - 4) add up to equal 90. So with that information, we can write a problem.
x + 6 + 3x - 4 = 90
Add the x's.
4x + 6 - 4 = 90
Combine the 6 and 4.
4x + 2 = 90
Subtract the two on both sides.
4x = 88
Finally, divide by 4.
x = 22
But by no means are we done yet. We still have to find out the entire angle MFE's measure, so we'll substitute 22, our new x value, into the equation for MFE - (x + 6)
22 + 6 is the new equation.
22 + 6 = 28
Angle MFE is 28°. I took the liberty of solving for the other angle, too, so I could check the answer. And as of my checking, this answer is correct because
62 + 28 = 90
I hope this answers your question.

The radius, R, of a sphere, is 6.3cm. Calculate the sphere's volume, V.
Use the value 3.14 for[tex]\pi[/tex], and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
1046.9
Step-by-step explanation:
The formula for calculating volume of a sphere is the following:
4/3·π·r³
The question asks for you to substitute 3.14 instead of using the exact number π.
∴V=4/3·3.14·6.3^3
V=1046.86344
Now round your answer to the nearest tenth:
1046.86344 -->1046.9
∴V=1046.9

Answer:
154°
Step-by-step explanation:
Angles formed from opposite rays and sharing a vertex are called "vertical angles." Vertical angles are congruent.
Angle 2 and the one marked 154° are vertical angles, so they have the same measure.
Angle 2 is 154°.

which of the following is true?
This shows that the function will be decreasing at the point where x < -6 or increasing at the point here x > 6
Increasing and decreasing functionGiven the rational function expressed as:
f(x) = x+6/x^2-9x+18
To determine the point where the function is decreasing, we will equate the numerator to zero to solve for the value of x
x + 6 = 0
x = -6
This shows that the function will be decreasing at the point where x < -6 or increasing at the point here x > 6

Given the function f(x) = –5|x 1| 3, for what values of x is f(x) = –12?
For the given function f(x) = –5|x + 1| + 3 the value of x = 2, -4
What will be the value of x?To find the answer to this question, we will have to find the values of x where:
-5|x + 1| + 3 = -12
We can solve this equation for x to find the values of x that satisfy this equation.
-5|x + 1| + 3 = -12
Subtract 3 from both sides.
-5|x + 1| = -15
Divide both sides by -5.
|x + 1| = 3
Now here, the equation will split off into two different equations. These two are:
x + 1 = 3
x + 1 = -3
Lets solve the first one first.
x + 1 = 3
Subtract 1 from both sides.
x = 2
Now we solve the second one.
x + 1 = -3
Subtract 1 from both sides.
x = -4
So now we have the answers x = 2 and x = -4.
So the values of x are x = 2, -4
