Your formula for this is

and

. Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.
So first you want to draw out you triangle and label everything so side a would be x, side b would be 15 and c would be x
next the angles need to be label
and finally the anwser is 150m
Answer:
A
Step-by-step explanation:
The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.
A property of equilateral triangles is the angles are congruent.
The sum of the 3 angles = 180°, hence the measure of each angle is
= 60° → A
