Question

Find 'x' in the following figures?
​

Answer 1

Answer:

The value of x is 67°.

Step-by-step explanation:

By exterior angle property of triangle,

x°+56°=123°

x°=123°-56°=67°

Answer 2

hey mate!

angle ACD + angle ACB = 180 degree (Linear pair)

so, 123 degree + angle ACB = 180 degree

so, angle ACB = 180 - 123 = 57 degree

Now, angle ACB + angle x + angle BAC = 180 degree ( Angle sum property of triangle)

so, 57 degree + angle x + 56 degree = 180 degree

so, angle x = 180 - ( 57 + 56) = 180 - 113 = 67 degree

so, angle x = 67 degree

hope this helps you

but the other answer given by the other user is also correct and a short way. So, both are right
