Given the triangle below, which of the following equations correctly representsthe relationship between a, b, and c?Triangle not drawn to scale A cz B az 2abcos (90.)b a2 c2 2abcos (90.)

Answers

The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:

c² = a² + b² - 2ab*cosC

Where a, b and c are the sides, while C is the angle opposite to side c.

In the triangle ABC, C = 90°, hence:

c² = a² + b² - 2ab * cos(90)

The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)

Which answer describes the restrictions for the variables?

x - 4 / x + 1

Answers

restrictions are not allowed values

the most common restrictions are sqrt of a negative and dividng by zero
since there are no sqrts in this quesiton, see whicch value of x will make us divide by zero
x-4/x+1
denom=0 to find restricted value
x+1=0
minus 1
x=-1

the restricted value is x=-1
basically
x=all real numbers except for -1
