Question 1134986
Sorry....<br>
The problem says to use YOUR calculator to evaluate the two trig functions.  WE can't use YOUR calculator; YOU have to do it.<br>
Notes:
(1) 30' is 0.5 degrees, so the angles are 2.5 and 87.5 degrees
(2) no calculator I know of calculates cotangent values; you will need to calculate 1/tangent(angle)
