I am currently working on some of these review problems in the section I have been able to solve some. I am having a problem setting up these three problems. On the attachment below you will find problem 2.148, 2.150 & 2.154 these are the ones which I am kind of stuck on.
2.148= 1110 & 29.7 deg
2.150 = 313 & 140
2.154 = 8.78 -6.59j-8.78k
Can some help me set up the problems?
Problem 2.148 and 2.150
