tan ∅ = opposite side/ adjacent side

   = 4/3

Answer 2

Answer:An expression is one or more terms in an algebraic phrase. An expression does not contain the = sign because it is a phrase. Some examples of algebraic expressions are 2x, 5x + 3, 8m - 5m + 10

Evaluate an Algebraic Expression

To evaluate an algebraic expressiontext annotation indicator for x = 3, means to replace the variable x with the number 3 and then simplify by following order of operations.

Example:

Evaluate the following expression for x = 3.

3 xtext annotation indicator + 5

3(3) + 5text annotation indicator

= 9 + 5

= 14

Write an Algebraic Expression

To write an algebraic expression, look for key words that tell you what operation (add, subtract, multiply, or divide) to use.

Example:

Write an algebraic expression for: The product of x and 5 .

The key word here is product . You may recall that a product is the answer obtained when you multiply. That means we want to multiply x and 5, so we write the expression as 5 x . It should be written the standard way by putting the coefficient in front of the variable.
