What is the lesson? We are aware that the 2 triangles are congruent, they also tell us what the two segments are equal to. Your best is to set up an equation making the segments equal to eachother to find the value of segment WK
Δ FCD is a right triangle ( 3² + 4² + 5² ).
10 : EB = 5 : 3
5 EB = 30
EB = 6
With Pythagorean theorem:
CE² = 10² - 6² = 10 - 36 = 64
CE = 8
ED = 5
AB = 2 · 5 = 10
Answer: The length of the side AB is 10.
(x - 5)(x + 5)(2x - 1)
= (x ^ 2 - 25)(2x - 1)
= 2x ^ 3 - x ^ 2 - 50x + 25
I got 8 but then I did it on my calculator and it said 12 so its 12
