Answer 2

☯GIVEN :

• a) 53°
• b) 45°
• c) 19°
• d) 69°
• e) 81°

☯TO FIND :

• Complement of each angles.

☯KNOWLEDGE REQUIRED :

• Two angles are said to be complementary , if the sum of two angles is equal to 90°.

➲SOLUTION :

Let complement in each case be x°.

• a) 53°

$\implies{ \sf{53 ^ {\circ} + x^ { \circ}= 90^ { \circ}} }$

$\implies{ \sf{ x^ { \circ}= 90 ^ { \circ}- 53 ^ { \circ}} }$

$\implies{ \underline{ \boxed{ \red{ \bf{ x^ { \circ}= 37 ^ { \circ}} }}}}$

$\huge {\pink{\therefore}}$ The complement of 53° is 37°.

• b) 45°

$\implies{ \sf{45^ {\circ} + x^ { \circ} = 90^ { \circ}} }$

$\implies{ \sf{ x^ { \circ} = 90 ^ { \circ}- 45^ { \circ}} }$

$\implies{ \underline{ \boxed{ \red{ \bf{ x^ { \circ}= 45 ^ { \circ}} }}}}$

$\huge {\pink{\therefore}}$ The complement of 45° is 45°.

• c) 19°

$\implies{ \sf{19^ {\circ} + x^ { \circ}= 90^ { \circ}} }$

$\implies{ \sf{ x^ { \circ}= 90 ^ { \circ}- 19^ { \circ}} }$

$\implies{ \underline{ \boxed{ \red{ \bf{ x^{ \circ}= 71 ^ { \circ}} }}}}$

$\huge {\pink{\therefore}}$ The complement of 19° is 71°.

• d) 69°

$\implies{ \sf{69^ {\circ} + x^ { \circ}= 90^ { \circ}} }$

$\implies{ \sf{ x^ { \circ}= 90 ^ { \circ}- 69^ { \circ}} }$

$\implies{ \underline{ \boxed{ \red{ \bf{ x^ { \circ}=21 ^ { \circ}} }}}}$

$\huge {\pink{\therefore}}$ The complement of 69° is 21°.

• e) 81°

$\implies{ \sf{81^ {\circ} + x^ { \circ}= 90^ { \circ}} }$

$\implies{ \sf{ x^ { \circ}= 90 ^ { \circ}- 81^ { \circ}} }$

$\implies{ \underline{ \boxed{ \red{ \bf{ x^{\circ}=9 ^ { \circ}} }}}}$

$\huge {\pink{\therefore}}$ The complement of 81° is 9°.
