For kite SPQR with SR = QR and SP= QP, find m

The measure of angle R is 58°.
What is the measure of angle R?
From kite SPQR, If SR = QR andSP= QP
Pair adjacent angles of a quadrilateral are equal to 180°
So,
SR = QR
122° + measure of angle R = 180°
measure of angle R = 180° - 122°
measure of angle R = 58°
Therefore, the measure of R is 58°
