Answer:
The second option.
Step-by-step explanation:
A^2+B^2=C^2
6.4^2+7.1^2=C^2
40.96+50.41=C^2
91.37=C^2
9.55 = c
6.5^2+7.2^2=C^2
42.25+51.84=C^2
94.09=C^2
9.7=C
78°
when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.
