Question

Which expression is NOT equal to the value of x in the right triangle shown?

x,. b,. c,. d,. a,.
A
b, d, over a,.
B
b squared over c,.
C
the square root of b squared minus d squared,.
D
A over b, c,.

Answer 1

I can’t tell which choice is wrong without seeing the triangle and how a, b, c, d, and x are placed. Can you either

- upload the diagram, or
- describe which segment each letter labels (which side is the hypotenuse, which are the legs, whether a or c or d are segments of the hypotenuse after an altitude, etc.)?

If it helps, here are the common right-triangle formulas you can check against once you tell me the labeling:

- Pythagorean: hypotenuse^2 = (leg1)^2 + (leg2)^2, so a leg = sqrt(hypotenuse^2 − other leg^2).
- Altitude from the right angle to the hypotenuse (h) and hypotenuse segments p and q:
- h = sqrt(p·q)
- (leg1)^2 = hypotenuse · p
- (leg2)^2 = hypotenuse · q
- h = (leg1·leg2)/hypotenuse

Upload or describe the figure and I’ll identify which option is NOT equal to x.
