Find a round the answer to the nearest hundredth

B:  41.11 degrees

Step-by-step explanation:

In this right triangle, the "adjacent side" has length 55 and the hypotenuse has length 73.  The trig function relating the adjacent side, hypotenuse and angle of a right triangle is the COSINE:

             adjacent side        55

cos A = =

              hypotenuse           73

This can be rewritten as cos A = 0.753.

Our task is to determine the angle A.  Most calculators in use today feature trig functions, including the inverse cosine function.  That function is the one we need to determine angle A from cos A = 0.753.

                      -1

Typing in cos      0.753, I get A = 0.718 radians.

Converting this to degrees yields 41.112 degrees.  This corresponds to possible answer B.
