Question

8. In the given figure, if :
(0)
a = 130°, find b.
(ii) b = 200°, find a
(iii) a = 5/3 right angle, find b.
​

Answer 1

Answer:

Step-by-step explanation:

(i) From figure, a + b = 360°

⇒ 130° + 6 = 360

⇒ 6 = 360°-130°

⇒ b = 230°

(ii) From figure,

a + b = 360°

⇒ a + 200° = 360°

⇒ a = 360° – 200°

⇒ a = 160°

(iii) Here, a= 5/3 right angle

= 5 /3 x 90° = 150°

a = 150°

Here, a + b = 360°

⇒ 150° + b = 360° (∵ a = 150°)

⇒ b = 360° - 150°

b = 210°
