In ΔBCD, \text{m}\angle B = (5x+14)^{\circ}m∠B=(5x+14)

, \text{m}\angle C = (x+19)^{\circ}m∠C=(x+19)

, and \text{m}\angle D = (2x+19)^{\circ}m∠D=(2x+19)

. What is the value of x?x?

Respuesta :

Answer:

x = 16

Step-by-step explanation:

m<B+m<C+m<D = 180°

5x + 14 + x + 19 + 2x + 19 = 180

8x + 52 = 180

8x = 180 - 52

x = 128/8

x = 16
