Final answer:
The question deals with the calculation of the area of a triangle given its dimensions. The area is determined using the formula Area = 1/2 × base × height, yielding an answer with the appropriate number of significant figures based on the given measurements.
Step-by-step explanation:
The subject of the question pertains to the area of a triangle and the application of trigonometric methods to find missing sides and angles in triangular land parcels, which falls under the topic of Mathematics. Specifically, the calculation of the base of a triangle given its height is a high school level geometry problem.
For the question asking about the area of the triangle where the base is 166 mm and the height is 930.0 mm, the area can be calculated using the formula: Area = 1/2 × base × height. Converting the base and height to meters gives us 0.166 m and 0.930 m respectively.
Therefore, the area is 1/2 × 0.166 m × 0.930 m = 0.07719 m². The answer should be expressed with five significant figures as both the base and height were given with four significant figures.
