Correct answer is A.
Points on angle bisectors are equidistant from sides of a triangle. Since angle bisectors of a triangle meet in a point, that point is equidistant from all three sides of a triangle. Therefore, it is the center of a circle inscribed in a triangle.
Answer:
a) Yes.
b) Yes.
Step-by-step explanation:
Meredith and Hillary both want coffe, but they don't know if the other two people do, therefore they can't know if everyone want coffee. If they didn't want coffee, their answer would have been just "no".
Aly knows that she doesn't want coffee, therefore she knows that not everyone wants coffee.
Answer: 60°
<u>Step-by-step explanation:</u>
∠5 and ∠2 form a Linear Pair so their angles are supplementary.
∠5 + ∠2 = 180
130 + ∠2 = 180
∠2 = 50
∠2 + ∠3 + ∠4 = 180 <em>Triangle Sum Theorem</em>
50 + ∠3 + 70 = 180
∠3 + 120 = 180
∠3 = 60
Hello!
First of all, we can subtract the stretching time. This gives us 20. If we divide by the four laps we get 5 minutes per lap.
Now, one lap is 400 meters (most tracks are), which is equal to 15,748.03 inches. This means it takes her five minutes to walk 15,748.03 inches. This is also equal to 300 seconds, so it takes her 300 minutes per 15,748.03 inches.
But if we round our big inches number to the nearest ten thousandth, we get 16,000, so in a simpler form her pace is 300/16,000. But we need to find in per second. Therefore we will divide by 300 to find how many inches she walks per second. This means she walks about 53.33 inches per second.
I hope this helps!
