Question

The leg of a right triangle is 2 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?

Answer 1

Pythagorean theorem = a^2 + b^2 = c^2

2^2 + b^2 = 4^2

4 + b^2 = 16
-4 -4
b^2 = 12
Square root

b = 3.5 rounded to the tenths place

The leg is 3.5 units

Hope this helps!
