Question

find the value of x in the following figure from lines and angles
​

Answer 1

Answer:

As AC is a line and ray BA stands on it

therefore 150°+BAC=180°[linear pAir]=30°

similarly angle ACB=70°

angle a + angle b +angle c =180°

30°+70°=100°

as AB is a line and ray CB stand on it

therefore x°+ABC=180(linear pAir)

therefore x=100

the value of x is 100

hope this will help u now.

Answer 2

Answer:

X=100°

Step-by-step explanation:

In triangle ABC

< A +150°=180°

<A=180°-150°=30°

<C+110°=180°

<C=180°-110=70°

<B+x=180°

<B=180°-x

<A+<B+<C=180°[angle sum property]

30°+180°-x+70°=180°

30°+70°+180°-180°=x

30°+70°=x

x=100°
