Answer:
x = 25
Step-by-step explanation:
The other angle in the triangle would equal 130 because the sum of angles in a triangle add up to 180.
2x + 130 = 180 because it is a linear pair
2x = 50
x = 25
In expression form this is:
9 + 2f

Tan θ = -3/4.
In 4th quadrant, sin θ is negative.
Therefore, sin θ = -3/5
