Answer:

Line 6

Step-by-step explanation:

The graph intersects at (-5, 16) and (2, 2)

Because she needs to plug the x's back into the equation

so $16 = -2(-5) + 6$ or $16 = -5^{2} + -5 - 4$

and $2 = -2(2) + 6$ or $2 = 2^{2} + 2 - 4$

Find the exact value of sin G

ad-work [718]

We need to find the value of the hypotenuse in order to solve this problem.

12^2+4^2=H^2

Therefore:

H=√(144+16)

H=4√10

Now:

sin(G)=O/H=4/(4√10)

=1/(√10)

=(√10)/10
