Cotθ= tan30° find theta

scoundrel [369]

Answer:

Step-by-step explanation:

Cot is the same as 1/tan so:

$1/tan(theta) = tan(30)$

By rearranging the equation, we get:

$1/tan(30) = tan(theta)$

By taking the inverse tan, we get:

$theta = tan^-1 (1/tan(30)) =60$

Ilia_Sergeevich [38]

Division is the inverse of multiplication; therefore it depends on knowing the multiplication table.

The problem of division is to find what number times the Divisor will equal the Dividend. That number is called the Quotient. (Lesson 11.) To find the quotient, there is a method called short division.
