In ∆ABC, m∠A = 60º, m∠C = 30º, and AB = 6 inches. What is the length of side BC?

1 answer:

7 0

The degrees let you know this a right angle with angles being 30 60 90 the side across 60° is x (square root)3
The side across 30° is x
6 is on opposite side of angle c 30°
So bc will be x (squareroot) 3
6 (squareroot)3

An ordered pair tells us what about a system of equations ?

mash [69]

Answer:

Step-by-step explanation:

It may not tell you anything. You have to be careful how you think about the answer to this. An ordered pair is just that: it describes an x and y value and that is really all that it does.

However it may also be used to describe the solution to a system of equations which cross in one place. For example, if you plot

y = x + 1

y = -3x + 2

The ordered pair that gives the point where both equations equal the same thing is (0.25,1.25) The graph is shown below, and the ordered pair marks the solution.
