Measure of angle ∠WXY = 107°

Step-by-step explanation:

Given a  WXYZ with  measure of ∠Y = ∠Z = 90° and ∠W=73°.

We have to find measure of ∠X .

Since, WXYZ is a closed figure having 4 sides, so it is a quadrilateral.

ANGLE SUM PROPERTY OF QUADRILATERAL

Sum of angles of a quadrilateral is always 360°

Thus, applying angle sum property to the given quadrilateral.

∠Y + ∠Z + ∠W + ∠X = 360°

90° + 90° + 73° + ∠X = 360°

253° + ∠X = 360°

∠X = 360° -253°

∠X = 107°

Thus, measure of angle ∠WXY = 107°
