OK, HERE GOES:

5y = 15

y = 15/5

Answer: y = 3

wow, i thought P4 Calculus would be harder than that.

BigMcnee you got it wrong man.

I got another GCSE A* question can anyone help.

A B and C are angles in a triangle. A = 60, B = 60. Find C

5y = 15

5y + x = 15 + x

(5y + x)/2 = (15 + x)/2

((5y + x)/2)^2 = ((15 + x)/2)^2

((5y + x)/2)^2

(5y + x)/2 = (((15 + x)/2)^2)^1/2

5y + x = 2(((15 + x)/2)^2)^1/2)

5y = 2(((15 + x)/2)^2)^1/2) - x

y = 1/5*2(((15 + x)/2)^2)^1/2) - 1/5*x

5y + x = 15 + x

(5y + x)/2 = (15 + x)/2

((5y + x)/2)^2 = ((15 + x)/2)^2

((5y + x)/2)^2

(5y + x)/2 = (((15 + x)/2)^2)^1/2

5y + x = 2(((15 + x)/2)^2)^1/2)

5y = 2(((15 + x)/2)^2)^1/2) - x

y = 1/5*2(((15 + x)/2)^2)^1/2) - 1/5*x

ok, here goes:

angles in triangle add up to 180 degrees always.

therefore: 180 degrees = 120 degrees - C

therefore: (180 - 120) degress = C

therefore: C = 60 degrees

or, you could realise that 60 + 60 + 60 = 180 as any1 would.

no really I need help. Just because your good at Maths and can do questions really easily, doesn't mean everyone else in the world is! We all have our own strengths and weaknesses, and my weakest subject is maths. Therefore something you find "piss easy", I could find very hard!

if u seriously find it hard then go to ur teacher and tell him/her u dont understand he cud give u extra lessons or help u after the lesson. you wont learn anything by just getting the answers.

But it is strange how you say there A* gcse questions when there quite easy and if they were A* type they would be harder ques. and if ur doing gcse maths. u shud know the answers or have a little clue about what the answer could be as you should of done that kind of maths when in the 3rd and 4th form. (yr 9 and 10)

Well, The Sentence:

All Angles In A Triangle Add Up To 180 Degrees Is Where The 180 Came From.

180 Degrees (all 3 Angles In Traingle) = (angle 1 ) + (angle 2) + (angle 3)

We Know 2 Angles. It Said A = 60, And B = 60

Therefore: 180 Degrees = 60 + 60 + Angle C

180 Degrees = 120 Degrees + C

We Need To Find Angle C, Therefore We Bring The 120 Degrees From The Right Side To The Left. Whenever We Reverse Something, I.e.) Swap The Side Its On, We Need To Reverse The Sign Infront Of The Value.

Therefore: 180 - 120 = Angle C

Which Solves: 60 Degrees = C

Understand. Or, If You Dont Get This "bringing The 120 From The Right Side To The Left Side", Then:

What Number Adds To 120 To Make Up 180.

Well Obviously Its 60, Therefore Angle C = 60 Degrees
