Answer:
Step-by-step explanation:
Since we are given a right triangle, we can use right trigonometric ratios.
<em>x</em> is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:
Substitute:
Solve for <em>x:</em>

Answer:
y = - x - 1
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - , then
y = - x + c ← is the partial equation
To find c substitute (12, - 4) into the partial equation
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - x - 1 ← equation of line
