If you had given the proper context of the question you would have got an answer much quicker.
You can't just copy the question bit without giving the background information - that contains vital information regarding the question. In this case it was the fact that the angles form an arithmetic sequence. I cannot see the paper/screen in front of you, nor can anyone else; we can only see what you type in as your question.
As there is a limited number of characters that can be used to ask a question you can't just copy the whole of the background information before the question as the question itself will get truncated off the end. You need to engage your brain and THINK about what the question is asking and what background information is needed and summarise it - as an example, look at how this question has been rewritten having found where you got your original question online - then it will be much easier for others to answer what you want, or you may actually realise what is needed anyway (can answer it yourself) and so improve your own cognitive reasoning and be better equipped to face the world.
------------------------------------------------------------------------------------------
An arithmetic sequence is one where there is a set amount added between each term - a common difference.
Let the first angle be a
Let the common difference be d.
The the three angles are a, a+d, (a+d)+d = a + 2d
The sum of the three angles is: a + a + d + a + 2d = 3a + 3d = 3(a + d)
The sum of the angles of a triangle is 180°.
Thus:
3(a + d) = 180°
→ a + d = 60°
Now, we know the first angle a, which is the smallest angle at 36°
→ a + d = 60°
→ d = 60° - a
= 60° - 36°
= 24°
Now we can work out the largest angle, the last in the sequence, which is:
largest = a + 2d = 36° + 2 × 24° = 84°
Not enough information. It isn't clear how many angles there are in your problem, or how they are related. The only thing that can be stated is that the largest angle has a measure that is at least 36.
The answer depends on the shape to which the angles belong. However, in most cases, the answer is indeterminate due to insufficient information.
However, one of my colleagues worked hard to find what he thinks was the original question which you should have posted rather than lazily cut and paste some incomplete and incoherent phrases.
If the smallest angle in a triangle forms an arithmetic sequence and measures 36 deg then the other two angles are 36 + x and 36 + 2x deg. Together, these add to 3*(36 + x) deg which equals 180 deg.
=> 36 + x = 60 => x = 24 and so the largest angle is 36+2*24 = 84 deg.
80
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.
It is 3.5 units.
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.
54 degrees
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.
The three angles are 40, 50 and 90 degrees.
When doing these types of problems, start with the fact that the sum of the angles in any triangle is 180 degrees (Any planar triangle that is.)So let the smallest angle be x. The largest angle is x+100 since we are told the largest angle is 100 degrees larger than the smallest angle.Now the third angle is x+5 by the same reasoning.So now we add x+x+5+x+100=1803x+105=1803x=75so x=25.The smallest angle is 25 degrees.The largest is 125 degrees and the third angle is 30 degree.Note that 125+25+30 is 180 as desired.
