Answer 1

Answer:

1.

By angle sum property of a triangle, we know that the sum of all sides of a triangle = 180°

Let the third angle of the triangle be of x°.

29° + 105° + x° = 180°

134° + x° = 180°

x° = 180-134° = 46°

46° is the answer.

2.

Let the third angle of the triangle be x°.

x° + 55° + 75° = 180°

x° = 180-130° = 50°

Now the exterior angle + Interior angle = 180°.

(As they stand on a line.)

180-50° = 130°

130° is the answer.
