The two triangles will be similar (same shape, and each side of one triangle the same multiple of the corresponding side of the other triangle), but not necessarily the same size.
The key word here is "similar;" be sure you understand what that means in trig.
The constant is a number by itself.....no variables
so the constant in y = 4x - 110 is : -110
First u have to expand the brackets...
4 x 2z = 8z
4 x 3 = 12
8z + 12 = 12
Then you have to get numbers on one side, and letter on the other...
8z -12 = 12-12
8z = 0
then u have to divide 8z by 8 to find 1z or just z.
z = (0/8) = 0
z=0
Hope this helps :)
14-20= - 6
5/7x-6=4/7x-4
5/7x-4/7x= 1/7x
1/7x-6=-4
-4+6= 2
1/7x divide by 2= so x= 14
