Question

pls someone answer me for the third question

Answer 1

Answer:

D = 120°

C = 108°

Step-by-step explanation:

D = 180 - 60 (opposite angles in cyclic quadrilateral)

D = 120°

Since A:C = 2:3

A = 2/3 C

A + C = 180 (opposite angles in cyclic quadrilateral)

2/3 C + C = 180

5/3 C = 180

C = 180 × 3/5

C = 108°
