Question

if tan (2x+30°)=1 then find the value of x​

Answer 1

Step-by-step explanation:

tan (2x+30°)=1

tan (2x+30°)=tan45

2x+30=45

2x=15

,x=7.5

Answer 2

The value of angle x​ = 7.5°

Step-by-step explanation:

We have,

$\tan (2x+30)=1$

To find,  the value of angle x​ = ?

∴ $\tan (2x+30)=1$

⇒ $\tan (2x+30)=\tan 45$

[ ∵ $\tan 45=1$]

⇒ 2x + 30° = 45°

⇒ 2x = 45° - 30°

⇒ 2x = 15°

⇒ x = $\dfrac{15}{2}$

⇒ x = 7.5°

∴ The value of angle x​ = 7.5°
