So given a problem where you have a triangle. One angle in the triangle is 4 times larger than another angle. How big are each of the angles?
So i set up the equation 4x+x+180-5x=180
One angle is 4 times large than another, hence 4x. The angles must add up to 180 because it's a triangle. The last one has to be 180 minus the the two others(4x+x). I see that the equation won't work because the x's cancel out, but i don't understand why this is not correct. I feel like I am missing out on something very basic and obvious but i can't seem to figure out what it is. Could someone help me out?
Btw i wasnt sure whether to put this here or in the homework section, Perhaps you mods could move it if it doesen't belong here?
