Which triangles could you use the HL Theorem to prove that triangle 1 is congruent to triangle 2?
suter [353]
Answer: D) III only

With figure I, we can't use HL (hypotenuse leg) theorem because we don't know if the two hypotenuses are the same length. We know that one pair of legs (the vertical legs) are congruent, but we don't have enough info

With figure II, we have two pairs of congruent legs. The tickmarks tell us this. However we don't know if the hypotenuses are congruent. Note: we can use the LL (leg leg) theorem, which is related to the HL theorem, but that's not what the teacher wants

Figure III is the only figure where we know that a pair of hypotenuses are the same length as shown by the similar tickmarks. The vertical legs are congruent as well for the upper pair of triangles. We have enough info to use HL.

Split £20 in the ratio 2:3
ValentinkaMS [17]

Hi friend,

The objective is to divide $20 in 2:3 ratio.

One part be 2x, another part is 3x

Sum of them = 20

2x + 3x = 20

5x = 20

x=4

So therefore one part must be 2x = 2 x 4 = 8

Another part = 3x = 3 x 4 = 12

Hence it is divided in 2:3 ratio.

Hope my answer is helpful to u. :)

The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:
pashok25 [27]

The information that provided by the graph are median and the range. The information that cannot be gotten from the graph is the mode.

The interquartile range is 25.

The outlier would distort the value of the median and mean.

<h3>How can a box plot be interpreted?</h3>

The information that can be derived from the box plot are the minimum value, maximum value, range, median, first quartile and third quartile.

The interquartile range is the difference between the first quartile and third quartile.

Interquartile range = 60 - 35  = 25
