ayuden me urge por fabor

Answer 1

Tenemos.

2x + x + 1 + 3x - 2 + 2x + 25 = 360
8x + 24 = 360
8x = 360 - 24
8x = 336
x = 336/8
x = 42°

x + 1 =
42 + 1 = 43°

2x + 25 =
2 * 42 + 25 =
84 + 25 = 109°

y es un angulo exterior de la circunferencia

y =  (109° - 43°)/2
y = 66°/2
y = 33°

x/9 = 4/x
x. x = 4 * 9
x² = 36
x = +/-√36
x = +√36
x = 6
 o
x = - √36
x = - 6
Solucion (6 , - 6)

5/2x = 4/13
5 * 13 = 4(2x)
65 = 8x
65/8 = x
Solucion
x = 65/8
