Complex numbers zj and zz are given by zj = 3- j2, zz = - 4 + j3. (a) express zj and zz in polar form. (b) find lz1l by first ap

inna [77]

Solution:

Given: zj = 3- j2, zz = - 4 + j3

Part a:

zj = 3- j2 = $3.6e^{-j33.7^{\circ}}$

zz = - 4 + j3 = $5e^{j143.1^{\circ}}$

Part b:

|zj| = |3− j2| = √3² +(−2)² = √13 = 3.60

|z1| = √(3− j2)(3+ j2) = √ 13 = 3.60.

Part c:

With the help of part a:

z1z2 = $3.6e^{-j33.7^{\circ}}.5e^{j143.1^{\circ}}$

The interior angles of a triangle have measures 75 degrees,(-5w+125) degrees, and (4w+85) degrees. what is the value of W?

andrew-mc [135]

The sum of the measures of the angles is 180 degrees.
75 + -5w + 125 + 4w + 85 = 180
Combine like terms.
285 - w = 180
Subtract 285 from both sides.
-w = -105
Divide both sides by -1.
w = 105
