how do I find theta in

tan(theta)=0.67

your calculator has a "2nd" or "INV" button.

Press it before hitting "tan"

or, use an online calculator to find arctan(0.67)
also, study up on the inverse trig functions.

To find theta in the equation tan(theta) = 0.67, you can follow these steps:

Step 1: Take the inverse tangent (also known as arctangent) of both sides of the equation. This will give you the angle in radians or degrees.

arctan(tan(theta)) = arctan(0.67)

Step 2: Use a calculator or a trigonometric table to find the inverse tangent of 0.67. Make sure your calculator is set to the correct angle unit (radians or degrees) based on your requirement.

arctan(0.67) ≈ 33.2 degrees (rounded to one decimal place)

Therefore, theta ≈ 33.2 degrees.
