The bottom angles are equal, so the sides are equal
2x = 5x-12
Subtract 5x from each side
2x-5x= 5x-12-5x
-3x = -12
Divide by -3
x = 4
YZ = 5x-12 = 5(4) -12 = 20-12 =8

answer: standard form is ax^2 + bx + c = 0
step-by-step explanation:
standard form is ax^2 + bx + c = 0
(2x + 1)(x - 2) = 0
distribute to get into standard form
2x^2 - 4x + x - 2 = 0
2x^2 - 3x - 2 = 0
a = 2, b= -3, c = -2
a is your answer
