Question

АВС, sin A = 0,2, b = 15, a = 20 см. Знайдіть sin B.

Answer 1

Ответ:

синус В ＝3/20

По теореме синусов

Answer 2

To find sin(B), we can use the sine rule, which states:

sin(A) / a = sin(B) / b

Given sin(A) = 0.2, b = 15 cm, and a = 20 cm, we can plug these values into the formula and solve for sin(B):

0.2 / 20 = sin(B) / 15

Now, let's find sin(B):

sin(B) = (0.2 * 15) / 20 sin(B) = 0.15

So, sin(B) = 0.15.
