Question

180°-a= ? если sin (a) = 5/13

Answer 1

Т.к sinα=5/13, то α=arcsin(5/13)
180-α=180-arcsin(5/13)

Answer 2

Given that sin(a) = 5/13, we need to find the value of 180° - a.

First, let's find the value of a using the inverse sine function (sin⁻¹).

sin⁻¹(5/13) = 22.62°

Now, we can find the value of 180° - a.

180° - 22.62° = 157.38°

Therefore, 180° - a is equal to 157.38°.
