Question

In figure find x....​

Answer 1

Answer:

x=10

Step-by-step explanation:

in triangle ABC=

A=30

B=??

C=70

sum of all sides of triangle =180°

A+B+C=180

30+B+70=180

180-100= B

B=80°

In triangle DBC=

it's given that B is divided into two equal parts...

Hence =40°

180=x+6x+70+40

180=7x+110

7x=180-110

7x=70

x=70÷7

x=10
