Step 4Find the angle from your calculator usingtan-1 Tan x° = opposite/adjacent = 300/400 = 0.75 tan-1of 0.75 =36.9°(correct to 1 decimal place) Unless you’re told otherwise, angles are usually rounded to one place of decimals. ...
The value of tan 30 degrees as a fraction is 1/√3. But we can rationalize the denominator by multiplying and dividing by √3. Then we get tan 30° = 1/√3 ×√3/√3 = √3/3. Thus, the value of tan 30 degrees in fraction form can be either 1/√3 or √3/3. ...
