Given that x = 25 cm and y = 7 cm, work out â BAC rounded to 3 SF.
I assume that y is one of the leg and x is the hypotenuse because that would look like a perfect Pythagorean triple.
And I assume that BAC is an angle and it is included in x and y.
And I assume that y is opposite to angle BAC
If I did not assume these I can't do anything with your question.
cos BAC = 7/25
BAC = 73.7 degrees,
Please try to give a more detailed question next time
