Answer 2

Write the measure of their complementary angles

i) 40°

• let it's complementary angle be "x"

Rule :

Complementary angles add up to 90°

$\longrightarrow\bf{ x + 40 = 90}$

$\longrightarrow\bf{ x = 90 - 40}$

$\longrightarrow\bf{ x = 50}$

• Therefore complementary angle of 40 is 50 .

ii) 63

• let it's complementary angle be "x"

Rule :

Complementary angles add up to 90°

$\longrightarrow\bf{ x + 63 = 90}$

$\longrightarrow\bf{ x = 90 - 63}$

$\longrightarrow\bf{ x = 27}$

• Therefore complementary angle of 63 is 27.

iii) 55°

• let it's complementary angle be "x"

Rule :

Complementary angles add up to 90°

$\longrightarrow\bf{ x + 55 = 90}$

$\longrightarrow\bf{ x = 90 - 55}$

$\longrightarrow\bf{ x = 35 }$

• Therefore complementary angle of 55 is 35 .

iv) 90

• let it's complementary angle be "x"

Rule :

Complementary angles add up to 90°

$\longrightarrow\bf{ x + 90 = 90}$

$\longrightarrow\bf{ x = 90 - 90}$

$\longrightarrow\bf{ x = 0 }$

• Therefore complementary angle of 90 is 0.
