Question

Find the value of x,y and z

Answer 1

Answer:

....

Step-by-step explanation:

x=90

z=150

y=120

Answer 2

$i)\: z + 30 = 180 \: \: \: \: \: \: (linear \: pair)$

$z = 180 - 30$

$z = 150$

$ii)\: x + 90 = 180 \: \: \: \: (linear \: pair)$

$x = 180 - 90$

$x = 90$

$iii)\: 90 + 30 + < 1 = 180$

$< 1 = 180 - 120$

$< 1 = 60$

$iv)\: 60 + y = 180 \: \: \: (linear \: pair)$

$y = 180 - 60$

$y = 120$
