An isosceles triangle has congruent sides of 20 cm. The base is 10 cm. Find the height of the triangle. Leave your answer in simplified radical form.

5√15cm or 19.36cm

Step-by-step explanation:

An isosceles triangle has two congruent sides.

The height of an isosceles triangle is also the median and the perpendicular bisector of the triangle dividing the base in half and forming two congruent right triangles.

a squared + b squared = c squared

5 squared + h squared = 20 squared

25 + h squared = 400

h squared = 375

h =√375

h = 5√15 cm

h = 19.36 cm

understand that i don't know the answers

will someone answer his question

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
