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

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 = ≈ 9.2 ( to the nearest tenth )

9.22

Step-by-step explanation:

Since it's a 90° triangle .

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 = 9.22

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

you divide them and then you get the answer i took this class this year
