Question

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.

Answer 1

Answer:x=13.42

Step-by-step explanation:

from Pythagoras principle we have

x^2=√(18^2-12^2)

x^2=√(18x18-12x12)

x^2=√(324-144)

x^2=√(180)

Take the square root of both sides

x=13.42
