cot(69) = 0.3839, approx.
69 degrees is an acute angle because it is greater than 0 but less than 90 degrees.

Five of the six exterior angle measures of a nonregular hexagon measure 55, 60, 69, 57, and 57. what is the measure of the unterior angle adjacent to the sixth exterior angles?
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
one angle will be 69 degrees while the other angle will be 111 degrees.
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
69 is already a whole number. A whole number is an integer without a fraction.
