Exercise 12 Page 644

Notice that the given figure is a 45^(∘)-45^(∘)-90^(∘) triangle.

19.5sqrt(2)

Practice makes perfect

Consider the given right triangle.

In a 45^(∘)-45^(∘)-90^(∘) triangle, the legs are congruent and the hypotenuse is sqrt(2) times the length of a leg. With this information, we can find the value of x. x= sqrt(2) * 19.5 ⇔ x=19.5sqrt(2)
