Which type of isometry is the equivalent of two reflections across intersecting lines?
a. glide reflection
b. rotation
c. reflection
d. none of these

That would be rotation

Your answer is c. 31°. this is because angles on a straight line add up to 180°, so we can subtract 93 from 180 to get 87°. then we know that angles in a triangle add up to 180° also, so we just add together 62° and 87°, which makes 149°, and then subtract 149 from 180 which is 31.i hope this !
