Given that Cos60=sin30=1/2 and cos30=sin60=root3/2.Evaluate tan60-1/1-tan30

root(3)

Step-by-step explanation:

assuming there are parentheses. (tan60-1)/(1-tan30)

tan 60 = sin 60 / cos 60 = root(3)

tan 30 = sin 30 / cos 30 = root(3)/3

answer = (root(3) - 1)/(1- root(3)/3)

simplify/ rationalize denominator, root(3)

There's a more "simple" way to get the answer, but this solution is the most straightforward.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
