PQRS is a square. find the value of x and y.

Ivan

Answer:

x = 7

y = 3/2 or 1.5 (IF THE ANGLE IS 30 BY THE RATIOS OF A RIGHT TRIANGLE.)

hope it's right

Step-by-step explanation:

FOR X:

Let's solve your equation step-by-step.

4x+3=31

Step 1: Subtract 3 from both sides.

4x+3−3=31−3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

x=7

FOR Y:

Step 1: Simplify both sides of the equation.

(3)(7)+6y=30

21+6y=30

6y+21=30

Step 2: Subtract 21 from both sides.

6y+21−21=30−21

6y=9

Step 3: Divide both sides by 6.

6y/6=9/6

y=3/2
