Answer:

Step-by-step explanation:

Let's do this step by step!

The hyponteuse is 7.7 because it is the longest side of a 90 degree angle.

the formula for this would a^2 + b^2 = c^2

 3.3^2 + b ^2 = 7.7^2

 10.89 + b^2 = 59.29

- 10.89            - 10.89       subtract from both sides

  b^2 = 48.4

[tex]\sqrt{b} = \sqrt{48.4} \\[/tex]

b = 6.95701085237

round to the nearest tenth ---> 7
