Help plzzzz

Answer 1

\[\sqrt{c ^2-a^2}=b\]

Answer 2

\[\sqrt{2^2-9^2}=\]

Answer 3

\[\sqrt{4-81}= 8.02\]

Answer 4

right

Answer 5

Depends on if you're teacher wants it in decimal form or not.

Since it says exact value its probably best to leave it as \[\sqrt{77}\]

Answer 6

Oh and, since it's in quadrant 4, and we are looking for the y value, it's negative

Answer 8

Sin = opposite/hypotenuse

So sin = \[\frac{ -\sqrt{77} }{ 9 }\]
