How do you know that 50 is not a perfect square?

1 answer:

6 0

We can always do a prime factoring of it, and check

50 = 2*5*5
2*5²

a perfect square, so-called, is the resulting number of a squared value, well 50 is not the result of anything squared, is the result of 3 factors, in this case 2,5 and 5.

a perfect square will be something like say 64, or 144, because

64 = 8*8
8²

144 = 12*12
12²

In ΔKLM, the measure of ∠M=90°, KM = 40, LK = 41, and ML = 9. What ratio represents the tangent of ∠K?

melomori [17]

Answer:

The ratio representing the tangent of ∠K is 40 : 9.

Step-by-step explanation:

Consider the right-angles triangle KLM below.

The angle M is 90°.

KM = perpendicular (<em>p</em>) = 40

ML = base (<em>b</em>) = 9

LK = hypotenuse (<em>h</em>) = 41

The tangent of an angle is the ratio of the perpendicular length to the length of the base.

Compute the tangent of ∠K as follows:

$tan (K)=\frac{p}{b}=\frac{40}{9}$

Thus, the ratio representing the tangent of ∠K is 40 : 9.

$( \frac{ - 8}{9} \times \frac{1}{ - 5} ) + (\frac{ - 8}{9} \times \frac{ - 7}{11} ) = \frac{ - 8}{9} \times ( \frac{1}{ - 5 } \times \frac{ - 7}{11} )$
