What expression gives the height, h, of the triangle?
2 answers:
Answer:
<h2>C.</h2>Step-by-step explanation:
In the given graph, we have an isosceles triangles, which height divides its side in two equal parts.
So, from the division, we have to equal right triangles, which on leg is 6, and its angle is 80°, being the height the other leg.
Now, to find the height, we have to use trigonometric reasons, specifically, the tangent reasons because involves a relation with both legs
So, we isolate to find its expression
If we compare with given choices, you'll observe that option C is the right answer.

Answer:
The size of file downloaded is <em>88 megabytes.</em>
Step-by-step explanation:
Given that:
Average rate of downloading the file =
Time taken to download =
Formula for the size of file downloaded =
Rate of downloading,
Time taken, = 110 seconds
To find:
Size of file downloaded in megabytes = ?
Solution:
First of all, let us apply the given formula to find the size of file downloaded:
Size of file downloaded =
Size of file downloaded = 800 kilobytes seconds 110 seconds =
<em>88000 kilobytes</em>.
Now, let us convert the unit kilobytes to megabytes to find the answer.
<em>Conversion formula:</em>
1000 kilobytes = 1 megabyte
Let us use unitary method to find the number of megabytes in 88000 kilobytes.
1 kilobytes = megabytes
88000 kilobytes = 88000 megabytes
<em>88 megabytes.</em>
Therefore, the size of file downloaded is <em>88 megabytes.</em>
