You can solve this with a proportion. If you know that 23 tagged alligators were in a 200 alligator sample, there are 90 tagged alligators in the entire river. Written otherwise:
23/200 = 90/x
and solve for x:
x = 782.608...
So the "best estimate" would be around 783 alligators. Hope that helps! If you liked this answer please rate it as brainliest!! thank you!!!

Answer:
Tan B = 12/5
Sin B = 12/13
Cos B = 5/13
Step-by-step explanation:
sine B = opposite (12)/hypotenuse (13)
= 12/13
Cosine B = adjacent/hypotenuse
= 5/13
Tangent B = opposite/adjacent
= 12/5

Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
