Finding the hypotenuse will be the resultant force: \[DeltaP=\sqrt{(-200)^{2}+100^{2}}=223.7=224N\] For the angle, we can use Sine function, giving us\[\sin \beta=\frac{ 200 }{ 224 }\] \[\beta=\sin^{-1} \frac{ -200 }{ 224 }=-63.2\] Given that you do not want negative angles, we use the property 90-B=90-63.2=26.7Degrees. Can you use the same methodology for the other exercises?
