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.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
