Question

Find the value of x so that -2, x, 8 are in A.P​

Answer 1

Answer:

Step-by-step explanation:

Apply

2b=a + c

2x=8-2

x=3

Answer 2

Now

Here z=80  

∘    (∵ vertically opposite angles are same)

Also z=t (∵ corresponding angles are equal)

⇒t=80  

∘

 And x & y are corresponding angles  

so x=y

Now y and z are corresponding angles  so y=z=80  

∘

 y=80  

∘

 ∵x=y So x=80  

∘
