Answer:
Keith travelled 4.2 miles if he had ridden directly to the pool
Step-by-step explanation:
Given: In a right triangle, the distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.
To find: Distance travelled by Keith if he moved directly from house to swimming pool
Solution:
ΔABC is a right angled triangle.
Using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular
![AC^2=AB^2+BC^2\\=3^2+3^2\\=9+9\\=18\\\Rightarrow AC=\sqrt{18}=4.2\,\,miles](https://tex.z-dn.net/?f=AC%5E2%3DAB%5E2%2BBC%5E2%5C%5C%3D3%5E2%2B3%5E2%5C%5C%3D9%2B9%5C%5C%3D18%5C%5C%5CRightarrow%20AC%3D%5Csqrt%7B18%7D%3D4.2%5C%2C%5C%2Cmiles)
