Question

ABCD is a cyclic quadrilateral. mLA= (4x + 25)° and mLC = (5x + 20)°
Find the value of x and mLC.
1 15: 75° (2) 15; 80° (3) 15; 85° (4) 15; 95°​

Answer 1

Answer:

Step-by-step explanation: as it is a cyclic quadrilateral the opposite side

angles are equal.so;

4x+25=5x+20

25-20=5x-4x

x=5

thereforemLC=5*5+20

                       =45
