Question

what is the size of the angle marked x in the figure show all the steps and give reasons​

Answer 1

Answer:

124 degrees

Step-by-step explanation:

As AC and AB are equal...

therefore by exterior angle property

angle C plus Angle A equals to x

and further by triangle angle sum

angle C equals to 66

add angle A and angle C

answer is 124

Answer 2

Answer:

58⁰+ c+ b =180⁰. ( sum of all angles in a triangle = 180⁰)

c = b (Given)

let c and b equals to x

58⁰ + 2x = 180⁰

2x = 180⁰ - 58⁰

2x = 122⁰

x = 61⁰

then,

angle x= 61⁰ - 180⁰. ( angles on a straight line)

x = 119⁰
