Step-by-step explanation:

Here

With reference angle 45°

hypotenuse (h) =x

perpendicular (p) = 5

Let

Sin45° = p/h

1/√2 = 5/ x

therefore x = 5√2

Now

b=?

Using Pythagoras theorem

b² = h² -p²

b² = (5√2)² - 5²

b² = 50 - 25

b² = 25

b² = 5²

Therefore b = 5

Now

tangent = p/b = 5/5 = 1

The length, in millimeters of each side of a square shaped electronic chip is a rational number. What statement is true about th
AVprozaik [17]

Answer:

The diagonal is irrational because it is a product of a rational and an irrational number

Step-by-step explanation:

The options are not given. However, the question is still answerable.

Given

Shape: Square

Length: Rational

Since the side length is said to be rational, I'll answer the question based on whether the diagonal is rational or not.

Having said that:

The diagonal (d) of a square with side length (l) is calculated using Pythagoras theorem.

d^2 = l^2 + l^2

d^2 = 2l^2

Take positive square root of both sides

d = \sqrt{2l^2}

Split:

d = \sqrt{2} * \sqrt{l^2}

d = \sqrt{2} *l

Recall that the side length (l) is rational.

However, \sqrt 2 is irrational.

So, the product of l and \sqrt 2 will be irrational

Hence:

The diagonal is irrational

(2x^3+16x^2-12x+9) ÷ (x+7)
madam [21]
Always eliminate the first one before moving on. Remember to drop down monomials, like you would a normal division problem.

                     2x² + 10x + 18
         __________________
x + 3 | 2x³ + 16x² - 12x + 9
         -(2x³ + 6x²)
         -------------------------------
                    10x² - 12x
                  -(10x² - 30x)
         -----------------------------
                            + 18x + 9
                          - (18x + 54)
                    ----------------------
                                      -45


  2x² + 10x + 18        R: -45/x + 3 is your answer R: = remainder


hope this helps
