Last one, use trigonometry to help you solve for y given that one side is 4 and there is an angle of 50 degrees.

y = 6.22

You can solve this in two ways.

1.) Use SOH CAH TOA:

I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.

2.) Use Law of Sines:

Solve for the last angle inside the triangle first.

Then use the angle you found (40°) in the equation.

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
