Question

solve this
find valueof x
​

Answer 1

Answer:

5x+ 30 = 180

5x = 150

x = 30

Answer 2

Given that ,

The AB is a straight line and

$\sf \mapsto \angle AOC = x + 10 \\ \sf \mapsto \angle COD =3x \\ \sf \mapsto \angle AOD = x + 20$

We know that ,

The measure of a straight angle is 180 degrees

Thus ,

$\sf \hookrightarrow x + 10 + 3x + x + 20 = 180 \\ \\ \sf \hookrightarrow </p><p>5x + 30 = 180 \\ \\ \sf \hookrightarrow </p><p>5x = 150 \\ \\ \sf \hookrightarrow </p><p>x = 30$

$\therefore \sf \underline{The \: value \: of \: x \: is \: 30 \: }$
