To get x intercept:
let y=0,x➖12=0,x=12
so x intercept point (12,0)
To get y intercept:
let x=0,3y➖12=0,y=4
so y intercept point (0,4)
51 x 8 = 408
It can be in this way: 51*8=408
Yes. If the side lengths are different, you can end up with different angle measurements (example: SSA~ property. You can have two sides that are the same but you can make two different triangles with those side lengths and that one angle.)
X is 35, if you follow the rules of alternate angles
Here is the solution..x equals to √3..which is equals to 1.73205
