Answer:
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
b = 6.95701085237
round to the nearest tenth ---> 7
