Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
Answer:
4=20.16, 5=129.96, 6=52.2
Step-by-step explanation:
38773 - 14056 = 24717
24717 + 14056 = 38773
Answer: 1/5
Step-by-step explanation:
So when multiplying fractions, you multiply both the numerators (top) and the denominators (bottom). So to keep the numerator 2, you must multiply it by 1 and to get 25 on the bottom, 5 X 5 = 25. So the answer must be 1/5
