Answer:
Answer is
sine = 0.769
cosine = 0.6389
Step-by-step explanation:
Given a right angle triangle
Where Height of triangle = 10
And Hypotenuse of triangle = 13
Then, we know Sin Ф = Height/ hypotenuse
or SinФ = 10/13
or Ф = arcsin (10/13)
or Ф = 50.285°
So , sin Ф = sin 50.285° = 0.769
Next we need to cosine.
i.e cos Ф = cos 50.285° = 0.6389
Hence we got, sine = 0.769
And cosine = 0.6389
