Question

in a cyclic triangle ABC twice the measure of angle A is thrice measure of angle C then find the measure of angle A​

Answer 1

angle A is opposite to angle C . according to the property of cyclic quadrilateral

the opposite angles are supplementary

that is a + c is =180

let a is x

C is 3x

a+c =x+3x

180= 4x

x = 180÷4

x= 45

measure of a is 45
