A is 3 times as large as b and 16 degrees larger than c what is the measure of each angle?
I suppose your talking about a triangle.
The angles of a triangle add up to 180 degrees.
So A + B + C = 180
If A is three times the size of B
and if A is C + 16 degrees
Then (3B) + B +(3B - 16) = 180
So, let's remove the brackets..... 3B + B + 3B - 16 = 180
Add the Bs and move the 16 to the other side of the
equation...
7B = 180 + 16
7B = 196
B = 196 / 7
B = 28
So now we know B we can work out the other angles...
A = 3B = 3 x 28 = 84
C = A - 16 = 84 - 16 = 68
A = 84
B = 28
C = 68
