Given rhombus abcd, find area if
angleabc = 60deg
ae = 2

All triangles are 30-60-90, therefore the short legs (2) are half as much as the hypotenuse. Therefore the hypotenuse is 4. Because its a rhombus, all sides are congruent, so you have the length and width and can multiply them to get 16 square units.

You have to put it into slope-intercept form.

4.5x-0.5y=3

1. Subtract 4.5x from both sides:
-0.5y=-4.5x+3

2. Divide both sides by -0.5 to leave the y variable on one side:
y=9x-6

3. Your linear equation is
y=9x-6

4. Graph (tell me if you need help on graphing!)
