Best ResponseYou've already chosen the best response.0Dividing an equilateral triangle in half leads to the next special triangle that we will look at. Consider the figure showing an equilateral triangle with a line dividing it down the middle. This line divides both the angle at the top of the triangle and the base of the triangle into two equal parts.

Best ResponseYou've already chosen the best response.0x=7. 7times square root 3 is the length of the altitude (dashed segment on drawing which everyone but me knows intersects at a right angle :))

Best ResponseYou've already chosen the best response.0i still do not understand how x=7 still . after we found that the value is about 12 how do we go from 12 to 7

Best ResponseYou've already chosen the best response.0so is this what you all mean b^2+ (7)^2=(14)^2

Best ResponseYou've already chosen the best response.0right but atjari said c=14 thats why im confused.. you said c^2=14
