An angle measures 31 . what is the measure of its complement?

Complement means that the sum of the angles equals 90°.

Let x represent the unknown angle, then

x + 31 = 90

   -31    -31

x         = 59

59°

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
