This in turn produces an unusual independence of mind, freeing the INTJ from the constraints of authority, convention, or sentiment for its own sake. INTJs are known as the Systems Builders of the types, perhaps in part because they possess the unusual trait combination of imagination and reliability.
Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question. Step 3 For Sine calculate Opposite/Hypotenuse, for Cosine calculate Adjacent/Hypotenuse or for Tangent calculate Opposite/Adjacent. Step 4 Find the angle from your calculator, using one of sin-1, cos-1 or tan-1.
When no angles are known, the cosine rule is the only option. Step 1: Begin by using the cosine rule to find the largest angle. NOTE: We find the largest angle first, because there can only be one angle in a triangle that is obtuse (greater than 90). If a triangle has an obtuse angle, then this will be it. The reason for finding it first is that in the next step we will use the sine rule to find the second angle.
