WebFor a given triangle to be a right angled, the sum of the squares of the two sides must be equal to the square of the largest side. (i) Let a = 9cm, b = 16 cm and c = 18 cm. Then . Hence the given triangle is not right angled. (ii) Let a = 7cm, b = 24 cm and c = 25 cm, Then . Hence, the given triangle is a right triangle. WebMar 14, 2024 · Here, we have to find the sine and cosine angles at A and C. First, we will use Pythagoras theorem to find the hypotenuse of a right angled triangle. Then we have to use the trigonometric ratios to find the sine and cosine angles at A and C. Formula used: We will use the following formulas: 1) Pythagoras theorem: \[A{C^2} = A{B^2} + B{C^2}\] how does family affect delinquency
