Answer:
114°
Step-by-step explanation:
First we have to calculate the value of c Then
3c - 84° + c = 180° <being co-interior angles >
4c - 84° = 180°
4c = 180° + 84
4c = 264°
c = 264° / 4
c = 66°
Now
<R = 3 * 66° - 84°
= 114°
<P = <R ( being opposite angles of rhombus )
<P = 114°
Hope it will help :)
