The value of a is 37°, the value of b is 34° and the value of c is 143° in the given triangle.
According to the question,
We have the following information:
We have a triangle with angles given.
We know that angle made on a straight line is 180° and the sum of all three angles of a triangle is 180°.
We also know that vertically opposite angles are equal.
So, a is vertically opposite to 37°.
So, the value of a is 37°.
Now, a and c make a straight line.
c = 180-37
c = 143°
a + b + 109° = 180°
37° + b + 109° = 180°
b+146° = 180°
b = 180-146
b = 34°
Hence, the value of a is 37°, the value of b is 34° and the value of c is 143° in the given triangle.
