Answer:
y = 15
Explanation:
JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.
In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.
This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.
Solving for y.
Angle J is congruent to angle P.
5y - 4 = 71 Add 4 on both sides.
5y = 71 + 4
5y = 75 Divide both sides with 5.
y = 15
(Btw your solution for x is wrong.)
