Step-by-step explanation: I would suggest using the app Photomap for this kind of stuff. You take a picture of an equation and it gives you a step by step explanation and the answer. Glad I could help!
If each side of the square below is 8 inches, the probability that a point chosen at random in the square is in the blue region would be 0.25.
we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Alternate interior angles are congruent
see the attached figure with letters to better understand the problem
in this problem
the parallel lines are the lines a and b
the transversal line is the line c
so
the alternate interior angles are the Angle
and Angle 
m∠3=m∠6
therefore
<u>the answer is the option</u>
Angle
and Angle
