Given , ⊙A ≅ ⊙V
To find:
What congruency statements can you make? Check all that apply.
BC ≅ ZY
∠ DAB ≅ ∠ ZVX
BE ≅ ZX
Solution:
Consider the attached figure while going through the following steps.
If two circles are congruent, then their corresponding chords are also congruent along with the congruent intercepted arcs.
⇒ BC ≅ ZY
and
⇒ BE ≅ ZX
Answer:
a^2-12a+36
Step-by-step explanation:
;)
First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
Answer:
192 minutes
Step-by-step explanation:
24,000 times .4 = 9600
9600 / 50 = 192
