If sinx=4/5 and x is in quadrant 2, then tan2x= -12/7 24/7 -24/7 12/7

Hence, the value of tan2x is:

                            24/7

Step-by-step explanation:

We are given sine trignometric ratio as:

Aklso the angle ''x'' lie in the second quadrant.

As we know that the trignometric ratios which are positive in second quadrant are:

Sine(sin) and cosecant(csc)

whereas the other trignometric ratio's i.e. cosine(cos),secant(sec),cotangent(cot),tangent(tan) are all negative in second quadrant.

We know that the sine trignometric function is the ratio of perpendicular to hypotenuse of a right angled triangle corresponding to angle 'x'.

i.e. Let P=4 and H=5

As we know that in a right triangle we have:

Also as we know,

(The value is negative as tangent is negative in second quadrant)

Also, we are asked to find the value of:

We know that:

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
