Question

Q6. find the complementary angles of given angles
(a) 30°
(b) 45°​

Answer 1

Answer:

Complementary Angle90°

a)90=30°+x

x=90°-30°

=60°

b)90°=45°+x

x=90°-45°

=45°

Answer 2

Answer:

a) 30° -

Let us consider the complementary angle of 30° be x,

30° + x = 90°.........(Sum of two complementary

angles is 90°)

x = 90 - 30

x = 60

Therefore, the complementary angle of 30° is 60°

b) 45°

Let us consider the complementary angle of 45° be x,

45° + x = 90............(Sum of two complementary

angles is 90°)

x = 90 - 45

x = 45°

Therefore, the complementary angle of 45° is 45°
