Question

Find the side length, b. Round to the nearest tenth.

Answer 1

Answer:

b ≈ 9.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² = a² + c² = 6² +7² = 36 + 49 = 85 ( take the square root of both sides )

b = $\sqrt{85}$ ≈ 9.2 ( to the nearest tenth )

Answer 2

Answer:

9.22

Step-by-step explanation:

Since it's a 90° triangle $c^{2} =a^{2} +b^{2}$.

In this example they labeled the hypotenuse as b instead of c are equation is still the same just put the correct variables in the right places.

$b = \sqrt{6^{2} +7^{2} }$

b = 9.22
