Help me please?! its math question
1 answer:
X = 23 Angle H= 39° Angle I = 118° Angle J = 23° The sum of all angles inside a triangle is 180°. Your equation: (2x -7) + (5x + 3) + x = 180 2x + 5x + x - 7 + 3 = 180 8x - 4 = 180 Your equation in its simplest form: 8x - 4 = 180 Solving for x: 8x - 4 = 180 8x = 184 x = 23 Angle H = 2x - 7 2(23) - 7 = 46 - 7 = 39 Angle I = 5x + 3 5(23) + 3 = 115 + 3 = 118 Checking the math: 39 + 118 + 23 = 180 Please let me know if you have questions.
