A straight ladder of length 7.1 m rests against a vertical wall. A person climbing the ladder should be "safe" as long as the foot of the ladder make s an angle of between 70° and 80°with the horizontal ground. Determine the minimum and maximum heights hat the ladder can safely lie against the wall.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
