9. The triangle of forces given below is made up of the forces P and Q and the resultant force R= P + Q. (The diagram is not to scale.) 109° R - 1 br 180 If ||||| = 49 N and the force makes an angle of 18° with the horizontal, ||0|| = 31 N and the force makes an angle of 109° with the horizontal, then the angle 0 in degrees (rounded to two decimal places) that the re- sultant force R makes with the horizontal is equal to: (a) 51, 30° (b) 89. 11° (c) 84, 15° (d) 103, 37° (e) 70,95°
