Since the equation says "cos(x-2)", we know that the horizontal displacement is 2 units.
Angles in a triangle sum to 180 degrees
180 - 90 - 20
= 70 degrees
A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.
90 square inches i think!!!
3x-2y=7
3x=7
x=7/3
-2y=7
y=-7/2
so...(7/3,-7/2)
