I need one clarification: is the given side √7 a leg or the hypotenuse? Here are both possibilities:
- If √7 is a leg: in a 45-45-90 triangle hypotenuse = leg·√2, so
x = √7·√2 = √14 ≈ 3.7 (to the nearest tenth).
- If √7 is the hypotenuse: a leg = hypotenuse/√2, so
x = √7 / √2 = √(7/2) ≈ 1.9 (to the nearest tenth).
Tell me which side is labeled √7 and I’ll confirm the correct value.
