Hello,
C(5,10)= 10!/(5!*(10-5)!)=36
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
Answer: 12
Step-by-step explanation:
If you subtract 6 dollars from 50, you’ll get 44. 44 minus 12 three times is equal to 8
Take 8/20 and multiply it by the number of minutes in an hour (60)
6/20 x 60/1
360/20
simplify. divide both numbers by the GCF, 20.
360/20 / 20/20
18/1
there are 18 minutes (1080 seconds) in 8/20 of a hour.
