Question

Find the complement of each of the following angles:
57 deegee
20 deegree 63 deegree​

Answer 1

Answer :

• Sum of complementary angles is always 90° .

a) 57°

$\implies \sf Complement\:=\:90°-\:57°$

$\implies \sf Complement\:=\: 33°$

b) 20°

$\implies \sf Complement\:=\:90°-\:20°$

$\implies \sf Complement\:=\:70°$

c) 63°

$\implies \sf Complement\:=\:90°-\:63°$

$\implies \sf Complement\:=\:27°$

Answer 2

Answer:

lets make a equation

(1)57°+x°=90°

transposing 57 to right side

x=90-57

x=33

the ans is 33° for first angles

(2) 20+x=90

transposing 20 to right side

x=90-20

x=70

the ans for this angle is 70°

(3) 63+x=90

transposing 63 to right side

x=90-63

x=27

the ans is 27° FOR THIS ANGLE
