What is m∠HLK? thanks
Katen [24]
The answer is 80°.

If there is a line segment in a triangle which cuts two sides in half or if there is a line segment between two midpoints of a triangle's sides, that line segment must be parallel to the remaining side.

In this case, point L is the midpoint of FH, and point K is the midpoint of HG. So, LK is parallel to FG.

When a line cuts two parallel lines, there are angle pairs which are equal. In the problem above, the line segment FH cuts KL and GF.

The angles KLH and GFH are what we called "Corresponding Angles" and they are equal.

So if HFG is 80°, HLK must be equal to 80°

Which of the following ratios is equivalent to 49:35?
Arte-miy333 [17]

The best way to find it is to reduce each ratio you work with to its
lowest terms,and see which ones are equal. To reduce a ratio to its
lowest terms, divide each number by their greatest common factor.

First, the one that you're trying to match:  <u>49:35</u> .
The greatest common factor of 49 and 35 is 7 .
Divide each number by 7 . . .  <em>7:5</em> . . . <u>that's</u> what you have to match.

<u>7:4</u>
Their greatest common factor is ' 1 '.
No help at all, and this one is not it.

<u>14:25</u>
Again, their greatest common factor is '1 '.
No help at all, and this one is not it.

<u>21:15</u>
Their greatest common factor is ' 3 '.
Divide both numbers by 3 . . . <em>7:5 </em>.
That's it !
