Question

Fine the complement of each of the following angles.
55°
69° And
2/3 Of a right angle.​

Answer 1

$\large{\text{\red{A}}}{\text{\orange{N}}{\text{\green{S}}{\text{\purple{W}}{\text{\blue{E}}{\text{\pink{R}}{\text{\gray{:-}}}}}}}}$

55⁰ = Complementary angle - 55 = ❓

55⁰ = 90⁰ - 55⁰ = 35⁰

69⁰ = Complementary angle - 69⁰ = ❓

69⁰ = 90⁰ - 69⁰ = 21⁰

2/3 of a right angle = 90 × 2/3 = 60⁰

$\text{\red{So,}}$

60⁰ = Complementary angle - 60⁰ = ❓

60⁰ = 90⁰ - 60⁰ = 30⁰
