Answer:
-35, -20
Step-by-step explanation:
Because both lines AT and AN are tangents, they are equal to each other.
Because angle ATN is 70 degrees, then angle ANT is also 70 degrees
The 3 inside angles of a triangle = 180 degrees,
so angle A would = 180 - 70 - 70
Angle A = 180 -70-70 = 40 degrees
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.
Answer:
0.8889
Step-by-step explanation:
0.8889 is the 8/9 as a decimal rounded to 3 decimal places
1 mile = 1.609344... kilometer
2,180 miles = (1.609344... x 2,180 km)
