Answer:
Answer B
Step-by-step explanation:
Label the height = to y
All three triangles are similar.
Therefore 4/height as height /5 or
4/y =y/5 Cross multiply
y^2 = 20 Take the square root of both sides.
Now find x.
Solution
- The Pythagorean Theorem relates 4,y and x
- x^2 = y^2 + 4^2
- x = ?
- y^2 = 20
- x^2 = 20 + 4^2
- x^2 = 20 + 16
- x^2 = 36 Take the square root of 36
sqrt(x^2) = sqrt(36)
x = 6 Answer
B <<<< Answer
