Question

What will be the measure of supplement angle of the following angles :

(i) 100°
(ii) 90°
(iii) 55°
(iv) 125°

Answer 1

We know that sum of two supplementary angles are 180°. Therefore

(i) Supplementary angle of 100°
= (180° – 100°) = 80°

(ii) Supplementary angle of 90°
= (180° – 90°) = 90°

(iii) Supplementary angle of 55°
= (180° – 55°) = 125°

(iv) Supplementary angle of 125°
= (180° – 125°) = 55°
