The supplement of an acute angle is a/an __________ angle.
1 Acute
2 Obtuse
3 Right
4 Straight
Explanation:
Obtuse We know acute angle < 90° Let us take an example. \(\angle\text{x}=45^\circ\).....x is an acute angle. Supplement of x is 180° - 45° = 135° ....it is an Obtuse angle Obtuse angle > 90°.

Supplementary angle of 100° is:
1 180°
2 90°
3 80°
4 60°
Explanation:
80° Supplementary angles are two angles that have a sum of 180°. The given supplementary angle is 100° and we have to find other. Supplementary angle = 180° - 100° = 80°. \(\therefore\) Supplementary angle of 100° is 80°.

If two supplementary angles are in the ratio 2 : 7, then the angles are :
1 35°, 145°
2 70°, 110°
3 40°, 140°
4 50°, 130°
Explanation:
40°, 140° Let the angles be 2x and 7x Angles are given supplementary 2x + 7x = 180° 9x = 180° x = 20° So the angles are 2 × 20° = 40° and 7 × 20° = 140°
