Answer 1

Answer:

answer for the 1st qn i only know

Solution:

Let the the required  angle = x

Sum of complementary angles = 90

So, complement of of an angle x =  (90 − x)°

Sum of supplementary angles =180

So. supplement of an angle x =  (180 − x)°

By the problem:

 

\\ \Rightarrow \frac13(180-x)=(90-x)\\\\ \Rightarrow 180-x=3(90-x)\\\\ \Rightarrow 180-x=270-3x\\\\ \Rightarrow 3x-x=270-180\\\\ \Rightarrow 2x=90\\\\ \Rightarrow x=\frac{90}{2}=45^o

\therefore Required angle = 45°
