I have attached the diagram that is related to this question.
Answer:
perimeter of the triangle = 24 units
Explanation:
Using the grid, we can note that:
RS = 6 units
ST = 8 units
We know that the triangle inscribed in a circle is a right-angled triangle. Therefore, we can use the Pythagorean theorem to get the third side as follows:
(RT)² = (RS)² + (ST)²
(RT)² = (6)² + (8)²
(RT)² = 100
RT = 10 units
Now, we can get the perimeter as follows:
perimeter = RS + ST + RT
perimeter = 6 + 8 + 10
perimeter = 24 units
Hope this helps :)
