Sam is planting a garden that measures  square root 6.5  feet in width and  square root 9.8feet in length. which is the best estimation for the area of sam's garden using a rational approximations

If value of cos330° is √3/2 then find tan165°.

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
