Explicación paso a paso:
Hay que agregar expresiones algebraicas para entender los ejercicios. Igualamos a 90, 180, 360; dependiendo del angulo completo. Hallamos x y reemplazamos en los valores
1. 2x + x = 90 2. 4x +x = 90 3. 3x + 5x = 90
3x = 90 5x = 90 8x = 90
x = 90/3 x = 90/5 x = 90/8
x = 30 x = 18 x = 11.25
2x = 2(30) = 60 4x = 4(18) = 72 3x = 3(11.25) = 33.75
x = 30 x = 18 5x = 5(11.25) = 56.25
4. x + x + 20 = 90 5. x/3 + x/2 + x = 90
2x = 90 - 20 6 [(x/3) + (x/2) + (x) ] = 90 (6)
x = 70/2 2x + 3x + 6x = 540
x = 35 11x = 540
x = 35 x = 540/11
x + 20 = (35) + 20 = 55 x = 49.1
x/3 = 49.1/3 = 16.37
x/2 = 49.1/2 = 24.55
x = 49.1
6. 5x + 4x = 180
9x = 180
x = 180/9
x = 20
5x = 5(20) = 100
4x = 4(20) = 80
