Answer 1

Answer:

use Angle sum property of triangle

(i )45°+45°+ anglec =180°

90°+ angel c=180°

angel c=180°-90°

angel c=90°

Answer 2

answer

1 . m angle c = 180 - ( 45 °+ 45° ) = 90°

2. m angle b =180° - ( 20° + 120° ) = 40 °

3. m angle b = 180° - ( 105° + 22° ) = 53°

4. m angle c = 180° + ( 75° + 75° ) = 30°

5. m angle a b c = 180° / 3 = 60°
