Answer 2

Answer:

Step-by-step explanation:

1)

Transposing

2)

2(x+4)=12

2x+8= 12

2x= 12-8

2x= 4

x= 4/2

x= 2

3)

20°, 70°

4)

∠4 & ∠5

∠1 & ∠5

5)

x = 55°(Vertically opposite angles are equal)

∠x + ∠y= 180° (As both angles are forming linear pair)

55°+y= 180

y = 180-55

y = 125°

Therefore, x is 55° and y is 125°.
