Calculated Output

Hypotenuse 5

Area 6

Angle at a (°) 36.87

Formula: c = √(a²+b²); angle = atan(a/b)

Step-by-Step Breakdown

1. Values used:

2. Leg a = 3

The math behind it

Hypotenuse = √(a²+b²); area = ½ab; the angle opposite leg a is atan(a/b).

Legs 3, 4 → hypotenuse 5, area 6.

Other angle?

The two non-right angles add to 90°.
