Explanation:

This looks like an essay question with no right answer.

There are two "special" right triangles:

isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2

30°-60°-90° triangle with sides in the ratios 1 : √3 : 2

These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.

Answer:

(x - 8)(x + 3)

Step-by-step explanation:

x² - 5x - 24

Consider the factors of - 24 which sum to give the coefficient of the x- term (- 5)

The factors are - 8 and + 3 , since

- 8 × + 3 = - 24 and - 8 + 3 = - 5

Use these factors to split the x- term

x² - 8x + 3x - 24 ( factor the first/second and third/fourth terms )

= x(x - 8) + 3(x - 8) ← factor out (x - 8) from each term

= (x - 8)(x + 3) ← in factored form

Answer:

16x^7+13x^3+2

Step-by-step explanation:

8x^3+9x^7+5x^3+2+7x^7

Add 8x^3 and 5x^3 (don’t add the exponents together )

13x^3+9x^7+2+7x^7

Add 9x^7 and 7x^7

13x^3+16x^7+2

Then put them in order from biggest exponent to smallest

16x^7+13x^3+2
