Answer:
See Below.
Step-by-step explanation:
In the given figure, O is the center of the circle. Two equal chords AB and CD intersect each other at E.
We want to prove that I) AE = CE and II) BE = DE
First, we will construct two triangles by constructing segments AD and CB. This is shown in Figure 1.
Recall that congruent chords have congruent arcs. Since chords AB ≅ CD, their respective arcs are also congruent:
Arc AB is the sum of Arcs AD and DB:
Likewise, Arc CD is the sum of Arcs CB and DB. So:
Since Arc AB ≅ Arc CD:
Solve:
The converse tells us that congruent arcs have congruent chords. Thus:
Note that both ∠ADC and ∠CBA intercept the same arc Arc AC. Therefore:
Additionally:
Since they are vertical angles.
Thus:
By AAS.
Then by CPCTC:
Answer:
IM LOOKING FOR THE ANSWER TO LOL
Step-by-step explanation:
Answer:
A. 6
B. 143
C. The words "less than", "equal to", and "no more than"
Step-by-step explanation:
For a, we would want to first make an equation to represent the problem. It appears you've already figured that out though, so lets solve it!
Subtract 56 on both sides.
-6m=-36
Now divide -36 by -6 to isolate m.
m=6
It will take her 6 minutes.
For B, we need to make another equation.
2.95b<450-28
First, we can subtract 28 from the total, because she has already spent $28.
Now our equation is 2.95b<422
Lastly, just divide both sides by 2.95 to isolate b.
Our solution is 143. So she can buy 143 batteries.
Lastly, for 13, we can say that the words "less than", "equal to" and "no more than" can indicate an inequality in a real word problem.
Hope this helps!
Answer:
I believe the answer is B
Ok so the triangle part is 10 but I don’t know what the rectangle part is but the formula for a rectangle is A=base x high
