Find the measure of F. A. 44 B. 88 C. 90 D. 46

A. 44º

Step-by-step explanation:

The sum of internal angles in a triangle is equal to 180 degrees, whereas the sum for a square is equal to 360 degrees. Given that three triangles depicted on figure constructs a square, it is to conclude that each is an isosceles triangle. The following relations are presented:

1) Given

2) , Given

3) Given.

4) Given.

5) Given.

6) 2) in 3)

7) Algebra

8) By 2)

9) Alternate internior angles.

10) By 8). Result

Hence, the answer is A.

i think this could be a possible answer (1 / 84) -1

good luck! : d
