Question

Sendo r//s, determine as medidas de x,y e z dos seguintes casos:

Answer 1

A) 50 + y = 180

Y = 180 - 50

Y = 130°

B) 35 + y = 180

Y = 180 - 35

Y = 145°

C) x + 36 = z

x = z - 36

Y = 5x

5x + Z + ( z - 36 ) + 5x = 360°

10x + 2z - 36 = 360

10x + 2z = 396

z = 396 - 10x / 2

z = 198 - 5x

x = (198 - 5x) - 36

x = 162 - 5x

6x = 162

x = 27°

Y = 5 . 27

Y = 135

z = 198 - 135

z = 63°
