Use a table of trigonometric values to find the angle è in the right triangle in the following problem. Round to the nearest degree, if necessary.

Question

cos è = 0.8192 A = 45 H =?

Answer 1

There should be a figure or description of what angle or side goes where. If one of the acute angles of the right triangle is
è = cos^-1 0.8192 = 35.0 degrees, the other acute angle is 55.0 degrees.

I have no clue where A andH are located
