Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

If the value of cos330°is√3/2 then find cos 165°.
