I think it is B (yes,SAS similarity theorem)
Answer:
a) If the spinner is fair, then each color must have the same probability, this means that the probability for each color is the number of times that the color (in this case blue) is in the spinner divided the total amount of colors in the spinner, then the theoretical probability for each color is:
Pt = 1/5 = 0.20
The experimental probability can be found by dividing the number of times that the spinner landed on a given color (in this case for blue we have 15 times) divided the total number of spins ( 50)
Pe = 15/50 = 0.30
B) As we increment the number of spins, we should see that the experimental probability gets closer to the theoretical probability.
Help you with what. You did not put any question.
Answer:
The only help I can give on this one is all the angles added up should be 180

Answer:
Sin A = 0.6896
Cos A = 0.7241
Tan A = 0.9524
Step-by-step explanation:
Using SOH-CAH-TOA
Sin A = Opposite / Hypotenous
= 20 / 29
= 0.6896
Cos A = Adjacent / Hypotenous
= 21 / 29
= 0.7241
Tan A = Opposite / Adjacent
= 20 / 21
= 0.9524
