    Maths Question

    Right I have a 3 sided triangle. I need to work of the value of a

    On the left hand side there is 65o in a bubble inside the triangle, on the right handside there is a circle outside the triangle saying 138o. and at the top of the triangle is the a.

    I know that triangles add up to 180, but whats the value of A? would it be: 138-65=73

    a=97.

    if you get me?
    no a is not equal to 97 hon :hugs:

    Just ignore me if I get it wrong but I think you would need to do;

    180-138=42o

    then you've got 2 values of the triangle 42o and 65o

    65 + 42 = 107

    therefore you would need to do 180-107 = 73o

    a=73o

    But I'm not too sure!
    Thats what i thought aswell, but im not sure, if he send a diagram ill be able to help

    I think he's saying that the 65o is given as an interior angle and 138o as an exterior angle and you've got to work out the interior angle and then work out the last value (a)

    are you sure he isn't looking for the lenght of the side of the triangle that is a?

    do you guys do sine rule at gsces?
    hayley isn't it the sine rule or am i too messed up with maths to know this is straightforward stuff?? maths was never meant to be hard :bawling:

    Im not sure, if its an angle its just basic adding/subtracting. If its a side then it will be the sine/cosine rule :s: But im sure thats not GCSE standard, and if it is its higher....
