saw5 [17]
B = 3h . . . . . . . .given by the problem statement
A = (1/2)bh . . . . formula for the area of a triangle

486 cm² = (1/2)*(3h)*h . . . substitute given information
(2/3)*486 cm² = h² . . . . . .multiply by 2/3
√324 cm = h . . . . . . . . . . . . . .take the square root

The height is 18 cm.
The base is 3*18 = 54 cm.

Rewrite −1 + 2i in polar form.
raketka [301]
The length of the radius would sqrt(1+4), or sqrt(5).
                                                                                           2
The angle would be in Quadrant II and would be arctan ------ , or arctan (-2).
                                                                                           -1

Find this angle using a calculator or table.

Then you end up with -1+2i = sqrt(5) angle arctan(-2).  The angle would be + and measured from the + horizontal axis.
