Question

If the sum of two angles is 71°. What will be the measure of third angle?

1. 109°

2. 60°

3. 125°

4. 38°

​

Answer 1

Answer:

1. 109 because sum of three angle is 180 and 180-71 gives 109

Answer 2

Answer:

109°

Step-by-step explanation:

Because we know the sum of the angle of the triangle =180°

and the sum of two angle is given =71

so the first two angle +third angle =180

so 71+ third angle =180

so third angle =180-71

=109

hence 1 is correct
