Adam has sticks of the following lengths: (3x+4) (2x+10) (x+12)cm He puts all 3 sticks together to make a triangle. The triangle is Isosceles. Calculate the 3 possible values of x.
Isosceles triangles, are triangles where two of the lengths are the same so we can say that: 1. (3x+4)=(2x+10) 2. (3x+4)=(x+12) 3. (2x+10)=(x+12) One of these must be true. Solve as simultaneous equations. 1. x=6 2. x=4 3. x=2
