Prove that sum of three angles of a triangle is 180 degree using this ...
Proof of Sum of Three Angles of a Triangle is 180 degrees:
- Let the three angles of a triangle be A, B, and C.
- According to the result, A + B + C = 180 degrees.
Finding the Value of x and Angles of the Triangle:
- Let the angles of the triangle be (2x-7), (x+25), and (3x+12) respectively.
- According to the sum of angles of a triangle, we have (2x-7) + (x+25) + (3x+12) = 180.
- Simplifying the equation, we get 2x - 7 + x + 25 + 3x + 12 = 180.
- Combining like terms, we get 6x + 30 = 180.
- Subtracting 30 from both sides, we get 6x = 150.
- Dividing by 6, we get x = 25.
Finding the Angles of the Triangle:
- Substitute x = 25 into the expressions for the angles:
- Angle A = 2(25) - 7 = 50 - 7 = 43 degrees.
- Angle B = 25 + 25 = 50 degrees.
- Angle C = 3(25) + 12 = 75 + 12 = 87 degrees.
Therefore, the value of x is 25 and the three angles of the triangle are 43 degrees, 50 degrees, and 87 degrees.
- Let the three angles of a triangle be A, B, and C.
- According to the result, A + B + C = 180 degrees.
Finding the Value of x and Angles of the Triangle:
- Let the angles of the triangle be (2x-7), (x+25), and (3x+12) respectively.
- According to the sum of angles of a triangle, we have (2x-7) + (x+25) + (3x+12) = 180.
- Simplifying the equation, we get 2x - 7 + x + 25 + 3x + 12 = 180.
- Combining like terms, we get 6x + 30 = 180.
- Subtracting 30 from both sides, we get 6x = 150.
- Dividing by 6, we get x = 25.
Finding the Angles of the Triangle:
- Substitute x = 25 into the expressions for the angles:
- Angle A = 2(25) - 7 = 50 - 7 = 43 degrees.
- Angle B = 25 + 25 = 50 degrees.
- Angle C = 3(25) + 12 = 75 + 12 = 87 degrees.
Therefore, the value of x is 25 and the three angles of the triangle are 43 degrees, 50 degrees, and 87 degrees.
