Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
Answer:
<u>66.22 </u>times 10=662.2
<u>4.03 </u>times 100=403
<u>0.108 </u>times 1000=108
Step-by-step explanation:
662.2 ÷ 10
403 ÷ 100
108 ÷ 1000
Answer:
Choice D:
Step-by-step explanation:
If we check them one by one...
Choice A is all correct, so we leave that there for now
Choice B's 3x12 is equal to 36, so therefore it's wrong
Choice C has the same mistake as Choice B - 3x12 is not equal to 32
Choice D is all correct, so therefore it is the answer
Though Choice A is also correct, the question asked for <u>all</u> of the different ways you can arrange the cars
So, therefore... the answer is A!

Answer:
2+32 (Or x)+16 = 50
Step-by-step explanation:
Answer:
(-9,-1)
Step-by-step explanation:
See the attachment. Use a graphing system such as Desmos and find the intersection of the 2 lines.
One may also solve them mathematically to insure the correct solution.
y = (1/3)x + 2
y = (2/3)x + 5
---
Since y = y:
(1/3)x + 2 = (2/3)x + 5
-(1/3)x = 3
x = -9
---
Use this value to find y:
y = (1/3)x + 2
y = (1/3)(-9) + 2
y = -1
=============
<u>(-9,-1)</u>
