Given: Cos θ = (3/5), Find: Csc θ

The value of is

Explanation:

Given that the function is

We need to determine the value of

The value of Opposite side of the triangle:

The formula for is given by

The value of opposite side can be determined using the formula,

Thus, the value of opposite side is 4

The value of :

The formula for is given by

Substituting the values, we have,

Thus, the value of is

The value of :

The formula for is given by

Substituting the values, we have,

Thus, the value of is

Hence, the value of is

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
