What are the roots of the equation x^2 + 30x = 1000?

20, -50

Step-by-step explanation:

In the given question, it is given that

ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.

And we have to find the value of tan B.

And tangent of any angle is equal to the ratio of vertical by horizontal. That is

And that's the required missing ratio for tan B .
