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

1.	What will be the measure of supplement angle of the following angles :(i) 100°(ii) 90°(iii) 55°(iv) 125°
Answer» 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°

What will be the measure of supplement angle of the following angles :(i) 100°(ii) 90°(iii) 55°(iv) 125°

Answer»

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°
