In ftr which side is included between r and f

Option (4) is correct.

Line segment RF lies in between ∠F and ∠R.

Step-by-step explanation:

Given : A triangle ΔFTR

We have to find the line segment that is included between ∠F and ∠R.

Consider the given triangle  ΔFTR

We draw the triangle as shown in attachment below.

Then we can see clearly that Line segment RF lies in between ∠F and ∠R.

Thus, Option (4) is correct.

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
