Check the picture below.
this is a case of the ambiguous case with an SSA, AC and CB are the sides and the angle is at A.
the ambiguous case has two triangles, the case when B is acute, CB sticks out, and the case when B is obtuse, CB sticks inside, it just so happen that those two angles for B are "supplementary" angles.
if you check the sin⁻¹ of that, we'll get the acute version of B, that's because of the constraints on the range of the inverse sine function, and we get ∡B ≈ 36.86989765°.
and of course, the other angle for B will be 180 - 36.86989765.

Answer: Where is question?
Step-by-step explanation:
Answer:
The mean is 21
Step-by-step explanation:
we know that
To find out the mean of the data set, sum all the values and divide by the number of values in the set
we have
Find the sum
Divide by the number of values in the set
N=8
so
