Question

find ths hypotenuse of a trianglewith a base of 11cm and a height of 9cm

Answer 1

You have to use the formula: a^2 + b^2 = c^2
9^2 + 11^2 = c^2
9^2 = 81
11^2 = 121
81 + 121 = 202
Now you find the square root of 202
That would be 14.2126704
But you can round it to 14.21

Answer 2

The hypotenuse of the triangle is 14.2126704 cm
