Answer: x^(2)-3x-28=0
Step-by-step explanation:
Reversing the clauses of an "if-then" statement only sometimes makes the new statement true, so it isn't true or false. For example, reversing the clauses of "if 1=x, then x=1" makes the new statement true, but reversing the clauses of "if x=2, then |x|=2" doesn't.

The given triangles are congruent by :
because they have Two Angles and a side between them equal to the corresponding Angles and side of the another triangle.
No,
although all the sides are the same length on an equilateral triangle the height is calculated by a straight perpendicular line at the mid point of the base.
The sides are not perpendicular with the base and are angled outwards
So you want to get t onto the right side so what you would do is subtract 8t from each side and add 8 to each side
-5t=20
Divide each side by -5
t= -4
