Find all values of x that make the triangles congruent. Explain your reasoning.
1 answer:
Answer:
x =
Step-by-step explanation:
If both the triangles ΔABC and ΔBCD are congruent,
Corresponding sides of both the triangles will be proportional.
5x(4x + 3) = (5x - 2)(3x + 10)
20x² + 15x = 15x² + 50x - 6x - 20
20x² + 15x = 15x² + 44x - 20
20x² - 15x² = 44x - 15x - 20
5x² = 29x - 20
5x² - 29x + 20 = 0
5x² - 25x - 4x + 20 = 0
5x(x - 5) - 4(x - 5) = 0
(5x - 4)(x - 5) = 0

Answer:
Step-by-step explanation:
y = ⅖x-2
slope of line is ⅖
slope of any perpendicular to line is -5/2
point-slope equation for line of slope -5/2 that passes through (-4,-3):
y+3 = (-5/2)(x+4)
