Triangles PRQ and MRN are not similar.

Step-by-step explanation:

The two triangles are PRQ and MRN.

It is given that both the triangles have ∠R = 90° as the common angle.

Now, we check whether the ratios of the sides are equal or not.

i.e. To check if

Since, we have the lengths,

PM = 8, MR = 10. Thus, PR = 8 + 10 = 18

QN = 14, NR = 7. Thus, QR = 14 + 7 = 21

So, we get,

implies

implies 1.8 = 3, which is not true.

So, the ratio of the sides are not equal.

Hence, we get that the triangle PRQ and MRN are not similar.

the answer is 5636.7

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
