Answer :

(i) We know that,

Sum of measures of complementary angles is 90^{o}

It is given in the question that,

Angle = 20^{o}

Therefore,

Complement = 90^{o} – 20^{o}

= 70^{o}

(ii) We know that,

Sum of measures of complementary angles is 90^{o}

It is given in the question that,

Angle = 63^{o}

Therefore,

Complement = 90^{o} – 63^{o}

= 27^{o}

(iii) We know that,

Sum of measures of complementary angles is 90^{o}

It is given in the question that,

Angle = 57^{o}

Therefore,

Complement = 90^{o} – 57^{o}

= 33^{o}
