Using trigonometry and the cosine rule the 3rd side works out as 37.77 cm and the smallest angle is opposite the smallest side which is 17.1 cm and it works out as 25.5 degrees.

Not always because the largest angle of a right angle triangle is between its smallest sides which measures 90 degrees

60 degrees, for an equilateral triangle, is the smallest interior angle.

The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.

Its 3rd angle is 52 degrees which is its smallest angle and opposite to its smallest side and by using the sine rule the perimeter of the triangle works out as 44.45 mm to two decimal places

The smallest angle of the triangle will be opposite the smallest side and using the cosine rule it works out as 17.9 degrees rounded to one decimal place.

The sum of the three included angles of a triangle always = 180 degrees. So if one angle = 180 degrees (a straight line) then the other two included angles will be = 0 degrees which cannot make a triangle.

It can have any value x degrees where 0 < x < 45.

It is 31.0 degrees.

in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
