Which cooking methods would work best if you are on a camping trip and have to build your own fire for cooking? What types of foods would you bring along that would work best with these
cooking methods and setting?

The best cooking methods would be to cook something simple, and reasonable for the campfire. Such as something that can cook in a pan or a pot. I wouldn't recommend frozen food.  Since the best cooking method is to cook something that can cook in a pan or a pot here are some suggestions. I would suggest hot dogs, soup, beans, grilled cheese sandwich, and for dessert s'mores of course.

Step-by-step explanation:

Hope this helps!! If you need to add sum you can.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
