Let's sketch the triangle.
The sides are a= 37.674 miles
b= 11.164 miles
c= 36.318 miles
We'll apply the cosine rule for angle calculations
(since the sine law cannot be employed without knowing any angle measurements).
The cosine law is given by
Substituting the values results in
C = 74.48°
We can find angle A using the sine law
A= 
A = 87.38°
The third angle B can be determined by calculating 180° minus the sum of angles A and C
B = 180 - 161.86
B = 18.14°
Thus, we have calculated all three angles (as shown in the attached figure).
Answer:
Area of land = 0.056 hectares
Detailed explanation: Knowing that
A typical person in the country requires 2,450 kilocalories each day. This means
An individual consumes 2450 kilocalories daily
The average kcal produced per hectare (ha) from the available food in the nation is 15,737,000 kcal/ha.
Thus, in one day, for one individual, we have
15737000 = 2450/hec
Hectare = 2450/15737000
Hectare = 1.5568 × 10 -4
The total land area required to provide sufficient kilocalories for a single person for one year in this developing country will be
Calculated hectare × 365.25
Hectare = 1.5568 × 10 -4 × 365.25
Area of land = 0.056 hectares

The following table presents the conversion from degrees to gradients.
To calculate the slope, we take the difference between the two y-values (gradients) and divide it by the difference between the corresponding x-values (degrees).
For this purpose, we will use the initial and final points listed in the table. Therefore, the slope m is calculated as:
After rounding to two decimal places, the slope of the line converting degrees to gradients is 1.11
Answer:
$18.56
Detailed solution:
The given distance from Oban to Stranraer is 178.9 miles.
First, determine the gallons of fuel consumed by dividing this distance by the vehicle's mileage (miles per gallon).
Next, calculate the total fuel expense by multiplying the amount of fuel used by the price per gallon, which is $0.83.
Hence, the total fuel cost for this trip amounts to $18.56.
