Question

56
Write the value of 'x' in the following figure.
123°
B value

C D​

Answer 1

Step-by-step explanation:

Given ∠BAC=56

∠ACD=123

[Straight angle]

∴∠ACB=180

−∠ACD=180

−123

=57

Consider △ABC,

By Angle Sum property, i.e, sum of all interior angles of a triangle =180

o

⇒∠A+∠B+∠C=180

⇒56

x+57

=180

∴x=67
