Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.
Answer:
56.5
Step-by-step explanation:
circumfrence is 2 pi R
If the radius is 9=R
then the circumfrence is 56.5
Answer:
if you draw LMN in the first quadrant, you need to draw L'M'N' in the third quadrant using the same coordinates as LMN but in the negative form.
The line you draw trough L and L' and both other two lines all go through the origin.
