The value of y is 60 (option b) 15=1/4y multiply both sides by 4 to get 60=y
A parallelogram has two sets of parallel lines and the opposite sides are equal. So, 1/4y=15. Multiply both sides by 4. (Reciprocal of 1/4.You have to reciprocate and multiply fractions instead of dividing.) y=60 The answer is B. y=60.
