Not enough information has been given to work out side A such as any of its angles upon which the sine rule could have been used to find side A but if the given triangle is a right angle triangle then side A is 28 which conforms to Pythagoras theorem for a right angle triangle.
The value of sin A is 5.82 and the actual angle is 19.47 degees
If the 13 is the longest side of that right triangle, then the missing side is 5 . If 'c' is the longest side of that right triangle, then the missing one is 17.692 (rounded).
By using Pythagoras' theorem for a right angle triangle if side AB is the hypotenuse it is the square root of 149 which is about 12.207 rounded to three decimal places
Using the cosine rule the 3rd side works out as 60.655 rounded to 3 decimal places
6.5 sqrt(3) = about 11.2583 (rounded)
Each side is: 16.65/3 = 5.55 cm Area is: 0.5*5.55*5.55*sin(60 degrees) = 13.34 square cm rounded
The answer rounded to the nearest tenth is 25 meters.
11.70
0.33
Area of triangle: 0.5*12*14*sin(134.6183417) = 16 square units rounded to the nearest whole number
Using the sine rule in trigonometry the perimeter of the triangle works out as 382cm rounded to the nearest integer
The value of sin A is 5.82 and the actual angle is 19.47 degees
If the 13 is the longest side of that right triangle, then the missing side is 5 . If 'c' is the longest side of that right triangle, then the missing one is 17.692 (rounded).
The length of each side is 9.2376 cm. (rounded)
6.4031 (rounded)
The numbers to the hundredths, on either side of the given number are: 34.12, which is 0.004 away, and 34.13, which is 0.006 away. So, the nearest is 34.12.
Sorry wrong question
