Question

Find the complement of the following angles:
b. (72-y)
a. (x + 22)​

Answer 1

Answer:

b. .

$90 - 72 + y = (18 + y) \: \degree$

a. .

$90 - x - 22 = (68 - x) \: \degree$

Answer 2

Answer:

b) (72-y)

Complement = 90°

Let us assume another angle as x

x + ( 72 - y ) = 90°

x = 90 - ( 72 - y )

x = 90 - 72 + y

x = ( 18 + y ) °

a) (x + 22)

Complement = 90°

Let us assume another angle as y

y + (x + 22) = 90

y = 90 - ( x + 22 )

y = 90 - 22 - x

y = 68 - x
