Question

I need someone good in trig. Please

Answer 1

And the question is...?

Answer 2

suppose theta is an angle in standard position whose terminal side lies in quadrant II. If cos theta - 112/13, find the value of tan theta.

Answer 3

@napalmgrenade

Answer 4

You need to post the problem correctly. The cosine of an angle cannot be -112/13 because the minimum value a cosine can have is -1

Answer 5

oops i meant 12/13

Answer 6

but its -12

Answer 7

Use the Pythagorean Theorem to find the missing side and then use the definition of tangent to find the tangent.

Answer 8

That's why I went to the left. Where do you think an x value of -12 is?

Answer 9

so its 12^2+13^?

Answer 10

a^2+b^2=c^2

Answer 11

yes so 12 would be a and 13 would be b for filling them in correct?

Answer 12

The longest side of a right triangle is always the hypotenuse. So:
12^2+b^2=13^2

Answer 13

144+b^2=169?
