For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find

For second question we have to find tan\Theta

In right triangle ABC as show in attachment,

tan\Theta = \frac{opposite side}{adjacent side} = \frac{AB}{BC}----(1)

Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So AB = \frac{1}{2}

Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So BC = \frac{\sqrt{3}}{2}

Plug these values in equation (1)

tan\Theta = \frac{AB}{BC} = \frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}}

To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

tan\Theta = \frac{1}{2} \times \frac{2}{\sqrt{3}}

Now 2 in top and bottom cancels out so we are left with

tan\Theta = \frac{1}{\sqrt{3}}

so thats the final answer for tan\Theta

To get the echo of a positive integer, we write it twice in a row without a space. For example, the echo of 2022 is 20222022. Is
Lynna [10]

The <em>echo</em> number 20222022202220222022 is the <em>perfect</em> square of 4496890281.

<h3>What echo number is a perfect square</h3>

An <em>echo</em> number has a <em>perfect</em> square if its square root is also a <em>natural</em> number. After some iterations we found that <em>echo</em> number 20222022202220222022 is a <em>perfect</em> square:

\sqrt{20222022202220222022} = 4496890281

The <em>echo</em> number 20222022202220222022 is the <em>perfect</em> square of 4496890281. \blacksquare

angelo rode his bike around a bike trail that was 1/4 of a mile long.he rode his bike around thetrail 8 times.Angelo says he rod
forsale [732]
Hi there!

From this problem we can pull out some key information and remove any excess.

- The trail is 1/4 of a mile long.
- Angelo rode around the trail 8 times.
- Angelo claims he rode 8/4 miles.
- Teresa claims he rode 2 miles.

From that we know that if Angelo rode around the trail 8 times and the trail is 1/4 a mile, he in total rode 8/4 of a mile.

However, Teresa claims he rode 2 miles!

And the answer is... they're both correct!

Angelo did indeed ride 8/4 miles however that is equivalent to 2 miles so they are both in the right.
