Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

\frac{\pi }{2} < t

if we apply the cosine function in the relation we get:

cos\frac{\pi }{2}

-1

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

cotan\frac{\pi }{2}

0

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0

Triangle GHI is similar to triangle JKL. If JP = 26, MH = 36 and PK = 16 then GM =
mars1129 [50]
Since the two triangles are similar, then the ratio of the corresponding sides is equal. Therefore;
JP/GM=PK/MH
26/GM = 16/36
   GM=  (26×36)/16
         =  58.5

Raise the fraction to the highest term 1/5 to 15ths=
PtichkaEL [24]

Raise the fraction to the highest term 1/5 to 15ths is \frac{3}{15}

<em><u>Solution:</u></em>

Given that we have to raise the fraction to the highest term 1/5 to 15ths

To raise a fraction to higher term, first you divide the larger denominator by them smaller denominator

Then multiply both the numerator and denominator by the same number, as a result that will give a new denominator.

Let "x" be the numerator of new fraction

\frac{1}{5} = \frac{x}{15}

To make the denominator 5 to 15 we have to multiply both numerator and denominator by 3

\frac{1 \times 3}{5 \times 3} = \frac{3}{15}
