Naturally, the answer you have crossed out will not be treated as your answer and hence you won't gain the mark.

Answer was Underroot 2. I wrote 1.5

Answer was Underroot 2. I wrote 1.5

its correct 2 i wrote the same

 

[farhan141]

1.5 is correct??

 

[KWIKIW]

No

 

[Kamihus]

1.5 is correct??

Yes, as it is non-recurring or non-terminating. If you mean you simply wrote 1.5 without the underroot, then its obviously incorrect.

 

[farhan141]

Lol I wrote only 1.5, that's the problem. I mixed rational and irrational

can anyone help me with Q28 of Maths N2011/12.................plzzzz its urgent

 

[farhan141]

whole Q2 (b)

Q.2(b)(i). Sum of interior angles = N-2 (180)

- 5-2 (180) = 540

- Let x be the angle AED, so angle EDC = 2x

- According to this, 2x + x + 110 + 70 + 120 = 540

- x = 80 (Angle AED)

Q.2(b)(ii) Sum of Angles in Triangle = 180

- Angle EDA = 10 + 80 + x = 180

- x = 90.

Hope it helps.
