Re: Logical question s
What is the sum of the angles in a triangle on a plane?

Re: Logical question s
270 degree because in triangle each is 90 and 3 sides so equal to 270 degree

That could only happen within spherical geometry, so try again...

Re: Logical question s
In triangle abc the angle a is three times the size of that at b and half the size of the angle at c.
Clarify, is b half the size of c or a is half the size of c?? Misplaced modifiers are confusing..

Re: Logical question s
I agree.
In triangle abc the angle a is three times the size of that at b and half the size of the angle at c. what is the angle at A???
A 30 b 36 degree c 54 deg d 60 degree
Assuming that we are talking about a and its relationship to b and c we can form the following equations:
a + b + c = 180
a + (a/3) + 2a = 180
Can you solve for a?

Re: Logical question s
????
Ok a+b+c=108
So why you put all a

Re: Logical question s

Correct!
Ok a+b+c=108, So why you put all a
An equation like a + b + c = 180 is likely to have an infinite number of solutions.
Thuis equation has only one.
a + (a/3) + 2a = 180
Can you solve for a?

Re: Logical question s
In triangle abc the angle a is three times the size of that at b and half the size of the angle at c. what is the angle at A???
A 30 b 36 degree c 54 deg d 60 degree
You start with
a + b + c = 180
It says a is 3 times b so a = 3b and b = (a / 3)
a + (a/3) + c = 180
Now the question says a = (1 / 2 ) c so c = 2a
a + (a/3) + 2a = 180
Now you solve for a.

Re: Logical question s
To check you go back to the original question:
In triangle abc the angle a is three times the size of that at b and half the size of the angle at c. what is the angle at A???
A 30 b 36 degree c 54 deg d 60 degree
We have found that a = 54 degrees, so b is what?

Re: Logical question s
a + b + c = 180
It says a is 3 times b so a = 3b and b = (a / 3)
