5x-13° ,::::;;== angle R
4x+4 ° ::;;==angle N
Since the quadrilateral is cylic and R and N are opposite to each other
Therefore
5x-13 + 4x+4 ==180 (sum of two opp. Angle of cyclic quadrilateral.
9x-9=180
9x=180+9
9x=189
x =189÷9
x=21
therefore angle ====
R=5x-13 == 5(21)-13 == 105-13 = 92°
N=4x+4==4(21)+4 = 84+4 =88°
4x+4 ° ::;;==angle N
Since the quadrilateral is cylic and R and N are opposite to each other
Therefore
5x-13 + 4x+4 ==180 (sum of two opp. Angle of cyclic quadrilateral.
9x-9=180
9x=180+9
9x=189
x =189÷9
x=21
therefore angle ====
R=5x-13 == 5(21)-13 == 105-13 = 92°
N=4x+4==4(21)+4 = 84+4 =88°
