Question

Geometry help please?! I would really appreciate it. Image attached below.

Answer 1

Well to do this, you would need to use Pythagorean theorem. \[a ^{2}+b ^{2}=c ^{2}\] So for this question, you would use the equation: \[5^{2}+8^{2}=c ^{2}\] Do you know what to do next?

Answer 2

it would be 25 + 64 = c^2
Which you would turn into 89 = c^2
So what would you do now to find c?

Answer 3

You would have to find the square roots of both sides to cancel out the ^2 with the c. \[\sqrt{89}=\sqrt{c ^{2}}\] Then this would turn into just \[\sqrt{89}\]
