If cos theta = 0.3090, which of the following represents approximate values of sin thetha for 0 degrees <90 degrees? A. sin t
artcher [175]

In this question, the given value is

cos \theta = 0.3090

And we have to find the value of sin theta and tan theta where theta is in first quadrant .

And in first quadrant, all are positive .

Now we use the formula, which is

sin \theta = \sqrt{1-cos^2 \theta} = \sqrt{1 - 0.3090^2} = 0.9511

And tan theta is the ratio of sin theta and cos theta, that is

tan  \theta = \frac{sin \theta}{ cos \theta} = \frac{0.9511}{0.3090} =3.078

So the correct option is B .

A pair of shoes is on sale for 80% of the original price the sale price is $60 what was the original price
Tom [10]
You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price
