Tcecarenko [31]
Answer:
I think it's 49 I'm sry if I'm wrong hope you luck
Step-by-step explanation:
J/9=5
Multiply both sides by 9
Which gets you
j = 45
Do you have a picture or some information of some sort?
What you do is multiply x and y by 4 so the new be point is (-36,24)
The two horizontal lines are parallel ( This is given by the red triangles)
Because the lines are parallel, the two angles 1 & 2 would be the same.
Set the two equations for the angle to equal each other and solve:
8y-6 = 7y
Add 6 to each side:
8y = 7y+6
Subtract 7y from each side:
y = 6
Now you have the value for y, solve for angle 2 by replacing y with 6:
Angle 2 = 7y = 7(6) = 42 degrees.
