Convert the complex number z = -12 + 5i from rectangular form to polar form.

Paha777 [63]

Answer:

$z=13(\cos 157\degree +i\sin157\degree)$

Step-by-step explanation:

The given complex number is

$z=-12+5i$

The polar form of this complex number is;

$z=r(\cos \theta +i\sin \theta)$ , where

$r=\sqrt{(-12)^2+5^2}$

$r=\sqrt{144+25}=\sqrt{169}=13$

and

$\theta =\tan^{-1}(\frac{5}{-12})$

This implies that;

$\theta=157\degree$ to the nearest degree.

Hence the polar form is

$z=13(\cos 157\degree +i\sin157\degree)$

Find the area of the triangle

Cerrena [4.2K]

Answer:

Part 1) $P=204\ yd$

Part 2) $A=1,325\ yd^2$

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

$P=54+97+53=204\ yd$

Part 2)

we know that

The area of triangle is given by the formula

$A=\frac{1}{2}(b)(h)$

we have

$b=53\ yd\\h=50\ yd$

substitute

$A=\frac{1}{2}(53)(50)=1,325\ yd^2$
