Answer:
2.2 cm
Step-by-step explanation:
You want the measure of the other leg of a right triangle with hypotenuse 3 cm and leg 2 cm.
Pythagorean theorem
For legs 'a' and 'b' and hypotenuse 'c', the Pythagorean theorem tells you the relationship is ...
a² +b² = c²
In the given triangle, we have a=2, c=3, so b can be found from ...
2² +b² = 3²
b = √(3² -2²) = √(9 -4) = √5 ≈ 2.2
The other leg is about 2.2 cm.
