Which is the best approximation for the value of √102?<br> A.10<br> B.11<br> C.50<br> D.51

Trava [24]

10, because when you use a scientific calculator you get 10.09950494
which would be round to 10 because after the decimal the number is 0 below 5 so 10 stays as 10

Cotθ= tan30° find theta

scoundrel [369]

Answer:

60

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:

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