If a point is the midpoint of a segment, then it divides the segment into two congruent segments. R is the midpoint of QS. Concl

DIA [1.3K]

Answer:

All given information leads to conclusion described on statement. ( $QR = RS$ )

Step-by-step explanation:

The strategy of problem consist in make a mathematical demonstration from given information. There are two assumptions: i) $R$ is a point of segment $QS$ and ii) $R$ is the midpoint of $QS$ . We proceed to perform the demonstration:

1) $R\in QS$ , $R$ is the midpoint of $QS$ . Given.

2) $Q - R = R -S$ Definition of midpoint.

3) $QR = RS$ Definition of segment/Result.

All given information leads to conclusion described on statement. ( $QR = RS$ )

(1+cos2x)/(1-cos2x) = cot^2x

sesenic [268]

We will turn the left side into the right side.

$\dfrac{1 + \cos 2x}{1 - \cos2x} = \cot^2 x$

Use the identity:

$\cos 2x = \cos^2 x - \sin^2 x$

$\dfrac{1 + \cos^2 x - \sin^2 x}{1 - ( \cos^2 x - \sin^2 x)} = \cot^2 x$

$\dfrac{1 - \sin^2 x + \cos^2 x }{1 - \cos^2 x + \sin^2 x} = \cot^2 x$

Now use the identity

$\sin^2 x + \cos^2 x = 1$ solved for sin^2 x and for cos^2 x.

$\dfrac{\cos^2 x + \cos^2 x }{\sin^2 x + \sin^2 x} = \cot^2 x$

$\dfrac{2\cos^2 x}{2\sin^2 x} = \cot^2 x$

$\dfrac{\cos^2 x}{\sin^2 x} = \cot^2 x$

$\cot^2 x = \cot^2 x$
