Sum of all the angles in the triangle has to be 180 degrees. Let's mark the largest angle as x. Then, smallest angle will be 0.5x and the middle one x-25. x + 0.5x +x - 25 = 180, which is after simplyfying: 2.5x = 205 x = 82 degrees -> the largest angle, x-25 = 57 degrees -> middle one, 0.5x = 41 degrees -> the smallest angle.
Largest = 86, Smallest 26
From smallest to largest is known as putting data in ascending order.
What are the numbers? you can put them from largest to smallest or Visa-Versa. it is called NUMERICAL ORDER
Start with the largest and end with the smallest
