Answer 1

Step-by-step explanation:

360-150=210

n-x=3°

n+x=210°

so the answer is none of these

its impossible... ok... hope you helpful

Answer 2

Answer:

According to sum of exterior angle property, we can say that:

• Sum of all exterior angle formed by a straight line is equal to 360°.

Therefore, according to the diagram:

⇒ 150° + n + x = 360° ...(i)

We are given that, n - x = 3°. Hence we can write it as:

⇒ n = 3° + x ...(ii)

Substituting value of 'n' from (ii) in (i) we get:

⇒ 150° + (3° + x) + x = 360°

⇒ 153° + 2x = 360°

⇒ 2x = 360° - 153°

⇒ 2x = 207°

⇒ x = 207°/2 = 103.5°

Hence the value of n is:

⇒ n = 3° + x

⇒ n = 103.5° + 3° = 107.5°

Hence the values of (n) and (x) are: 107.5° and 103.5° respectively.

Hence Option (d) is the correct answer.
