Question

Can you tell me the value of x in the figure given below with proper solution ?

Answer 1

Answer:

Angle ABC + Angle BAC = Angle ACD ( exterior angle is equal to the the sum of opposite interior angles)

x+100 + 2x-20 = 110°

3x + 80 = 110°

3x = 110 -80

x = 30/3

x = 10 °

Step-by-step explanation:

So , Value of X is 10 °

mark me brainliest

Answer 2

Sol:

Remote interior angle theorem

<B + <A = <C

(x + 10) + (2x - 20) = 110

3x - 10 = 110

3x = 110 + 10

3x = 120

x = 120/3

x = 40,,
