Solution

The correct option is B 40°
$Given, supplementary angle of ∠ A = 130 °$
Then, ∠A +130° = 180° [Sum of measure of supplementary angles is 180°]
∴∠A = 180° - 130° = 50°

We know that sum of measure of complementary angles is 90°
$So, complementary angle of ∠ A = 90 ° - ∠ A = 90 ° - 50 ° = 40 °$
