2. find the value of x and each angle.

Step-by-step explanation:

We have 2 angles that equal to 180, x and (x - 26).

Therefore:

x + (x - 26) = 180

Remember, when doing algebraic equations, we are doing PEMDAS backwards.

Simplify:

x + x - 26 = 180

Combine Like Terms:

2x - 26 = 180

Add:

2x = 206

Divide:

x = 103.

Proof:

(103) + (103 - 26) = 180

180 = 180

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
