Question

prove that the sum of three angles of a triangle is 180 segree. usind the result find the value of x and all three angle if the angles are (x+7)degrees (2x-25)degree and (3x-12) degree

Answer 1

Answer:

The sum of the three angles of a triangle is 180. ... Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation
