In any triangle ABC, if `a=18 , b=24 , c=30`, findcosA, cosB, cosC

Text Solution

AI Generated Solution

To find cos A, cos B, and cos C in triangle ABC where \( a = 18 \), \( b = 24 \), and \( c = 30 \), we can follow these steps: ### Step 1: Verify if the triangle is a right triangle We can use the Pythagorean theorem to check if the triangle is a right triangle. According to the theorem, in a right triangle, the square of the hypotenuse (the longest side) should be equal to the sum of the squares of the other two sides. \[ a^2 + b^2 = c^2 \] ...
