Could someone please help?Find the perimeter of each figure.

Create a set A with multiples of 5 that are less than 33.

(02.05)The figure shows three quadrilaterals on a coordinate grid: A coordinate plane is shown. Quadrilateral D has sides measuring 3 units and 1 unit. Quadrilateral F has sides measuring 3 units and 1 unit. Quadrilateral E has sides measuring 2 units and 6 units. Which of the following statements is true about the three quadrilaterals? D and E are similar but not congruent. E and F are similar and congruent. D and E are similar and congruent. F and D are similar but not congruent.

8+8i

9514 1404 393

**Answer:**

45. (8√2)∠π/4

46. (7√2)∠3π/4

**Step-by-step explanation:**

The polar form of a+bi is ...

a +bi ⇔ (√(a²+b²))∠arctan(b/a)

__

**45.** 8 +8i = (√(8² +8²))∠arctan(8/8) = **(8√2)∠π/4**

__

**46.** -7 +7i = (√((-7)² +7²))∠arctan(7/-7) = **(7√2)∠3π/4**

_____

*Additional comment*

The arctan function usually returns a value in the range -π/2 to π/2. The quadrant of the desired result can be determined by the signs of the components of the vector. For negative real parts, π needs to be added to the value that is usually returned by the arctan function.
