how do i solve this

Answer:
A = 61
Step-by-step explanation:
Complementary angles add to 90 degrees
A+B = 90
A +29 = 90
A = 90-29
A = 61
Answer:
∠A = 61°
Step-by-step explanation:
We know that sum of both angles of complementary angle is 90°.
∠A + ∠B = 90°
∠A + 29° = 90° ... (∠B = 29° - given )
subtract 29° from each side
∠A + 29° - 29° = 90° - 29°
∠A = 61°
