ABC is a right triangle, A is located at the origin, B is the right angle, AB = 12, and BC = 5. Find the coordinates of point C

horsena [70]

If B lies along the positive x-axis, then the coordinate of B is (12, 0). Since the right angle is at B and BC is 5, it means that C is 5 units above B.
Therefore, the coordinate of C is (12, 5)

Inverse equation t=120r/r+120 R=???

Answer:

r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

$t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}$
