Question

In the given figure find the value of theta if is equal to 20 CM BC is equal to 20 root 3 centimetre

Answer 1

Answer:

Required value of $\theta$ is 30°.

Step-by-step explanation:

From the properties of trigonometric functions :

• tanA = ( height for A ) / ( base for A )

Here,

= > tan$\theta$ = ( height for $\theta$ ) / ( base for $\theta$ )

= > tan$\theta$ = AB / BC

= > tan$\theta$ = ( 20 / 20√3 ) cm / cm

= > tan$\theta$ = 1 : √3

= > $\theta$ = tan30°

= > $\theta$ = 30°

Hence the required value of $\theta$ is 30°.
