Question

Find the value of x (in degrees) ​

Answer 1

we know that ,

angle ABC+ angle ADC= 180

=>40⁰+ angle ADC= 180⁰

=>angle ADC = 140⁰

SO,

X= 360⁰- 140⁰

=220⁰

Answer 2

Answer:

160

Step-by-step explanation:

produce a line from B to D such that BD is a bisector of angle B and angle D.

A+ABD=ADE

SO,70+20=90

DBC+C =CDE

20+50=70,

SO the value of ADC is ADE+EDC =90+70=160
