I just thought that I'd share this sun rise with the world﻿
Ok math Community I need some help.

A student that is at school wants to get home. Due to a fire in his area, he has to take an alternate route. He first drives 15 miles at a bearing of 42 degrees. Then, he travels 12 miles at a bearing of 140 degrees.

A. How far does he live from school?
B. On a normal day, what bearing should he take to get to school?
C. If the triangle represents the fire zone, what is the area of the fire zone in miles squared? ﻿

Denmark Scientists invented a New Material which can suck and release Oxygen in a room when needed.

Now you suddenly needed to vacuum all the oxygen from a room which caught fire and all you have to do is to place the "unnamed" material in the room and it will suck all the oxygen. Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. The stored oxygen can be released again when and where it is needed.

Professor Christine McKenzie and postdoc Jonas Sundberg, Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark have synthesized a material that absorb oxygen in large quantities and store it.Once it sucks up oxygen, it will hold on to it indefinitely until it's gently heated or exposed to low oxygen pressure, at which point it will quietly release its oxygen hoard back out into the atmosphere. About 10 liters of it would be needed to suck all of the oxygen out of an average-sized room.﻿
