Answer 1

Answer:Let θ be the angle between P and Q and R be the resultant vector. Then, according to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q. Now, expand A to C and draw BC perpendicular to OC. which is the magnitude of resultant. Here is u answers mate..... hope it helps u✌☺
