1. Properties of parallelogram Used: Opposite angles of parallelogram are congruent therefore ∠W = ∠S, so we have to substitute the given value by following the property of parallelogram cited above.
∠W = x + 15
∠S = 2x + 5
Solution: ∠W = ∠S
Substitute: x+15 = 2x + 5
x-2x = 5-15
-x = -10 divide by -1
x = 10
∠W = x + 15
∠S = 2x + 5
Solution: ∠W = ∠S
Substitute: x+15 = 2x + 5
x-2x = 5-15
-x = -10 divide by -1
x = 10
