Write the following complex number in polar form. express all angles in degrees rounded to the nearest tenth. 90 points. 15+15i

(21.2, 45deg.)

Step-by-step explanation:

plot 15+15i on an x-y plane, the radius to (0,0) = sqrt (15^2+15^2) = 15*sqrt(2)

radius = 21.2

angle from (0,0) to (15,15) is 45deg.

so the polar form is (21.2, 45deg.)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
