Question

If pqrs is a square solve for x what do I do?

Answer 1

x = 11

Explanation:

Properties of a square,

1). Diagonal of a square bisect the opposite angles.

2). All interior angles of a square measure 90°.

From these properties,

m∠PQR = 90°

Since, diagonal QS bisects angle PQR,

m∠PQS = m∠RQS = 45°

(6x - 21)° = 45°

6x = 45 + 21

6x = 66

x = 11
