If the angle of vision is more than 60° then you

Correct Answer - `198,33%`

(2) Less proteins and more waste products

C) 25 cm to infinity

C) A + d = i1 + i2 

Correct option is (B) 30° Let the angle be x. Then its complementary angle is 2x. \(\therefore\) x+2x = \(90^\circ\) \(\Rightarrow\) 3x = \(90^\circ\) \(\Rightarrow\) x = \(\frac{90^\circ}3=30^\circ\) Hence, the required angle is \(30^\circ.\)

Correct option is (B) 20° Let both angles are 2x and 7x. \(\because\) Both angles are complementary angles to each other. \(\therefore\) 2x+7x = \(90^\circ\) \(\Rightarrow\) 9x = \(90^\circ\) \(\Rightarrow\) x = \(\frac{90^\circ}9=10^\circ\) \(\therefore\) Required angle = 2x \(=20^\circ\)

Correct option is (A) 135° Let the required angle be x. \(\therefore\) Its supplementary angle is \(180^\circ-x.\) Now, complementary angle of \(180^\circ-x\) is \(90^\circ-(180^\circ-x)\) \(=x-90^\circ\) According to given condition, \(180^\circ-x=x-90^\circ\) \(\Rightarrow\) 2x = \(180^\circ+90^\circ=270^\circ\) \(\Rightarrow\) x = \(\frac{270^\circ}2=135^\circ\)

B) latent heat of vapourisation
