Solve for x in geometry

x = 3

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

28x - 2 is an exterior angle of the triangle, thus

28x - 2 = 15x - 3 + 40 = 15x + 37 ( subtract 15x from both sides )

13x - 2 = 37 ( add 2 to both sides )

13x = 39 ( divide both sides by 13 )

x = 3

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
