Answer:
m∠R = 118°
Step-by-step Step-by-step explanation:
Given:
- Quadrilateral PQRS is a kite.
- PQ = QR
- SP = SR
- m∠PSR = 88°
- m∠PQR = 36°
To find:
Solution:
Since one pair of opposite angles in a kite are equal, we can conclude that:
m∠SRQ = m∠SPQ
And
The 4 interior angles of a kite always sum up to 360°.
So,
m∠PSR + m∠PQR + m∠SRQ + m∠SPQ = 360°
Substitute the given value:
88° + 36° + m∠SRQ + m∠SRQ = 360°
Simplify like terms:
124° + 2m∠SRQ = 360°
Subtract 124° on both sides:
124° + 2m∠SRQ - 124° = 360° - 124°
2m∠SRQ = 236°
Divide both sides by 2.

m∠SRQ = 118°
So, the measure of ∠R is 118°.
