Question statement

Determine the lengths of the three sides and the measures of the three angles for the case when A = ({A[0]},{A[1]}), B = ({B[0]},{B[1]}), C = ({C[0]},{C[1]}). Length units are {units}.

Give numeric answers to engineering accuracy and measure angles in degrees.

Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

This variable doesn't seem to be used anywhere.

Part a) Gap-fill
Part b) Gap-fill
1. Gap Gap 0. Angle quantity
  Add
2. Gap Gap 1. Angle quantity
  Add
3. Gap Gap 2. Angle quantity
  Add

Ask the student a question, and give any hints about how they should answer this part.

The lengths of the three sides are:

AB = Gap 0.
BC = Gap 1.
CA = Gap 2.

Advice

Use the distance formula to find the lengths of the three sides.
Use the Law of Cosines to find one of the angles.
Use the Law of Sines to find the other two angles. Beware of the ambiguous case. Check your answers against the diagram.

Give a worked solution to the whole question.

Use this tab to check that this question works as expected.
