Question

Find the value of x in the givenright triangle.12x = [?1°х5Enter your answer as a decimal rounded to thenearest tenth.

Answer 1

We are given that we need to find the value of x based on two sides of a triangle (12 and 5).

We are given the side that is adjacent to the angle and the hypotenuse. This means we will use the cosine ratio (CAH).

Therefore, we will find the inverse of cosine at this value.

`\cos ^(-1)=((5)/(12))=65.37\approx65.4`

Therefore, the measure of x is equivalent to approximately 65.4 degrees.
