*see attachment for the figure referred to

Answer:

4 units

Step-by-step explanation:

Given that tan(f) = \frac{2}{1}, therefore, it follows that:

tan(f) = \frac{opp}{adjacent} = \frac{YW}{XW} = \frac{8}{XW},

If the ratio of YW to XW = 2:1, therefore, \frac{2}{1} = \frac{8}{XW}

Cross multiply to find XW

XW*2 = 8*1

XW = \frac{8}{2} = 4 units

guapka [62]

Step-by-step explanation:

\sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha)

Use the identity

\sin^2 \theta = \dfrac{1 - \cos 2\theta}{2}

on the left side.

\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)

\dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha)

Now use the identity

\sin \theta = \cos(\frac{\pi}{2} - \theta)

on the left side.

\dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha)

\frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha)

What does negative 4 over 7 &gt; −2 indicate about the positions of negative 4 over 7 and −2 on the number line?
mezya [45]

Smaller numbers sits on the left of greater numbers on the number line.

So, since

-\dfrac{4}{7} \geq -2

we're stating that -4/7 is larger and -2 is smaller. So, -4/7 sits on the right of -2 on the number line.
