Value of “x” in the adjacent figure.A) 12 B) 30C) 66D) 150

Answer»

Correct option is (B) 30

\((x+20)^\circ+3x^\circ+(x+10)^\circ=180^\circ\)

\(\Rightarrow\) \((x+20+3x+x+10)^\circ=180^\circ\)

\(\Rightarrow\) 5x + 30 = 180

\(\Rightarrow\) 5x = 180 - 30 = 150

\(\Rightarrow\) x = \(\frac{150}5\) = 30

Correct option is  B) 30
