In A Right Angled Triangle Abc The Hypotenuse Ab Is 10 M Long Whilst The Angle A Is 2748139

  1. In a right angled triangle ABC the hypotenuse AB is 10 m long, whilst the angle A is 70°. Calculate the remaining parts of the triangle.
  1. For the triangle illustrated below determine the angles B and C and the lengths of side b. Given information c = 466 m, a = 190.5 m and A = 22° 15’ 00”.

  1. The coordinates of stations A and B are as follows

E (m) N (m) A 1321.4 8257.7 B -146.4 7542.7
Calculate the length and bearing of the line AB.

  1. The coordinates of four survey stations are given below:

Station North (m) East (m) A 718 90 B 822 469 C 164 614 D 210 81
