Question

6. In a quadrilateral three angles are in the ratio 3:3:1 and one of the angles is 80°,
then other angles are
(0) 1200, 120°, 40°
(ii) 100°, 100°,800
(iii) 110°, 110°, 60°
(iv) 90°, 90°, 30°
7. If S and 100° form a linear pair. What is the measure of ZS
(0)
90° (iv) 80°
180° (ii)
120° (iii)

Answer 1

Step-by-step explanation:

3x+3x+1x+80° = 360°

7x+80° = 360°

7x = 360°-80°

7x = 280°

x = 280°/7

x = 40°

Therefore the angles are 120°,120°,40° and 80°
