Question

# In triangle $$ABC$$ above, the value of $$y$$ is twice the value of $$x$$, and the value of $$z$$ is three times the value of $$y$$. Calculate the value of $$x$$.

A
20
B
24
C
30
D
36

Solution

## The correct option is B $$20$$According to question: $$y°=2x°$$ and $$z°=3y°$$So $$z°=3(2x°)=6x°$$Now, sum of angles of triangle is $$180°$$So $$x°+y°+z°=180°$$$$\Rightarrow x°+2x°+6x°=180°$$$$\Rightarrow 9x°=180°$$So $$x°=20°$$Mathematics
