We would never have known of the Sun, Moon, Planets and stars.
Would even find it dificult to work out why it was dark at night. What a shock it would be when the first aircraft got above the clouds

Many natural things are harmful, such as E. coli, poisonous mushrooms and lots of other plants, rattlesnake venom, black widow spiders, etc., so "natural" doesn't really equate with good. Chemists can make most compounds (even the ones found in nature) and can make them extremely pure whereas even the good stuff from nature is of variable quality and often very impure. So, doesn't it follow that manmade chemicals are usually better than the same chemicals that occur in nature? What's wrong with "artificial" (synthetic or manmade)?

Triangle ABC is equilateral. Find the values of x, y, and z if angle A=19x+3, angle B=23y-3x, and angle C=5y+z. Show all work.

I'm not looking for you to do the problem for me, I just don't know what steps to take to solve the problem. Thanks.
