To find the missing angle using the inverse cosine (also known as arccos), you will need the cosine value associated with the given sides. Typically, in a triangle, the cosine of an angle is the ratio of the length of the adjacent side to the hypotenuse.
Assuming you are referring to a right triangle with adjacent side 50 and hypotenuse 27, we first calculate the cosine value:
\[
\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}} = \frac{50}{27}
\]
However, you cannot have a cosine value greater than 1, which implies that these side lengths (50 and 27) don’t form a valid right triangle (in fact, 50 should be less than the hypotenuse).
If you intended to refer to a different triangle configuration or to provide the lengths of the opposite and adjacent sides differently, please clarify.
On the other hand, if you are looking for the angle corresponding to a valid cosine value, please provide the correct lengths.
