Consider this equation (csc x+1)/cot x = cot x/(csc x +1) is it an identity?

1 answer:

7 0

Cross multiplying:-
cot^2 x = (csc x+ 1)(csc x + 1)

also cot^2 x = csc^2 x - 1 = (csc x + 1)(csc x - 1) (Known Identitiy)

so the equation is not an identity

What is the equation for the line of reflection that maps the trapezoid onto itself?

kvv77 [185]

The line that maps a figure onto itself is a line of symmetry of the figure.

From the given trapezoid, the line of symmetry of the trapezoid is x = -2.

Therefore, the <span>equation for the line of reflection that maps the trapezoid onto itself</span> is x = -2.

Answer:

Step-by-step explanation:

$\sqrt[3]{216}$ = $\sqrt[3]{8}$ · $\sqrt[3]{27}$ = $\sqrt[3]{2}$ ³ · $\sqrt[3]{3}$ ³ = 2 x 3 = 6
