A/c to trigonometric relations, sin(90 - x) = cos(x),
that means sin(90 - x) = cos(x) = 1/3.

Answer:

\sin(90^{\circ} - x)=\frac{1}{3}

Step-by-step explanation:

Given: \cos (x)=\frac{1}{3}

We have to find the value of \sin(90^{\circ} - x)

Since Given \cos (x)=\frac{1}{3}

Using trigonometric identity,

\sin(90^{\circ} - \theta)=\cos\theta

Thus, for  \sin(90^{\circ} - x) comparing , we have,

\theta=x

We get,

\sin(90^{\circ} - x)=\cos x=\frac{1}{3}

Thus, \sin(90^{\circ} - x)=\frac{1}{3}

Can u help me please better picture

Hi, there.

For this question, we can apply the Pythagorean theorem a^2 + b^2 = c^2.

I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.

Lengths a and b both have the value of 48, which means that the value s in \sqrt{2s^2} is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.

Plug in the value for c: a^2 + b^2 = (\sqrt{2s^2})^2

Plug in the value for s:

(\sqrt{2(48^2)})^2

Do the innermost exponents first:

(\sqrt{2(2304)})^2

The square root symbol and the power of 2 cancel each other out, so we are left with:

s = 2(2304), so the hypotenuse is 4608 inches.

Hope this helps!
