Answer:

height = 6.92820323028km (you can round if you want to)

Step-by-step explanation:

8km - 4km = 4km (this is for one of the side lengths of the traingle)

a² + b² = c²

4² + b² = 8² (b will be used to represent the height)

16 + b² = 64

b² = 48

b = 6.92820323028km

Find the slope of a line perpendicular to y = 3x + 7

Vikki [24]

Answer:

-1/3

Step-by-step explanation:

The slope of the line has the form y = mx + b where m is the slope. Here the slope is m = 3. A line perpendicular to it will have a negative reciprocal slope. The negative reciprocal of 3 is -1/3.
