Answer:
A.
isosceles, right
Step-by-step explanation:
perpendicular lines means that they make 90° angle with each other and for a triangle to be isosceles it has to have 2 sides of equal length
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
1 pint = 473.176 milliliters
62 x 473.176 = 215336.912 milliliters in a pony keg
215336.912/400 = 538.34 glasses
round off answer to 538 glasses
