Answer 1

Answer:

(12) (a) 150°

(13) 6.4 × $10^{-5}$

(14) (a) ₹ 400

Explanation:

(12) Three angles = 70°

Fourth angle = x°

70° + 70° + 70° + x = 360°

210° + x = 360°

x = 360° - 210°

x = 150°

Hence, your answer is a.

(13) 6.4 × $10^{-5}$

(14) 10 m of cloth = ₹ 1000

1 m of cloth = ₹ 1000 ÷ 10

= ₹ 100

4 m of cloth = ₹ 100 × 4

= ₹ 400

Hence, your answer is (a) ₹ 400
