A21-foot ladder is leaning against a building. the base of the ladder is 7 feet from the base of the building.
to the nearest degree, what is the measure of the angle that the ladder makes with the ground?

X - the measure of the angle that the ladder makes with the ground

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
