using an addition or subtraction formula to write the expression as a trigonometric function of one number tan(79)-tan(19)/1+tan(79)tan(19)= tanA= sqrt of B. What are A and B equivalent to.

Answer 1

This is the formula for tan(A - B); Thus, we need tan(79 - 19) = tan(60); I assume this is supposed to be in degrees.tan(60°) = √3 (tan = sin/cos and sin(60°) = √3/2 and cos(60°) = 1/2
