If the area A of a triangle is 60sq m (square meters) and the base b is 20m (meters) what is the altitude of h
umka2103 [35]

Answer:

<u>The altitude or height of the triangle is 6 meters.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Area of a triangle = 60 m²

Base = 20 m

2. What is the altitude (h) of the triangle?

Let's recall that the formula of the area of a triangle is:

Area = (Base * Height)/2

Replacing with the real values, we have:

60 = (20 * Height)/2

60 * 2 = (20 * Height) (Multiplying by 2 at both sides)

120 = 20 Height

Height = 120/20 = 6 meters

<u>The altitude or height of the triangle is 6 meters.</u>

Graph -3x + 9y = -27​
Svetllana [295]

Answer:

Step-by-step explanation:

The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.

-3x + 9y = -27

9y = 3x - 27

y = 1/3x - 3

By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.
