Answer 1

Answer:

CONCEPT OF SQUARES AND MULTIPLICATION.

Step-by-step explanation:

BY SEEING THE PHOTO ATTACHED BY YOU , I AM KEEPING THIS PHOTO IN CENTRE TO DO THIS SUM DO DON'T CONVEY THAT YOUR POLICY IS VIOLATED.

$\cot( \alpha ) = \frac{7}{8}$

NOW BY SQUARING ON BOTH THE SIDES ,

${ \cot^{2} ( \alpha ) } = ({ \frac{7}{8} })^{2}$

= BY SIMPLIFYING,

${ \cot^{2} ( \alpha ) } = \frac{7 \times 7}{8 \times 8}$

=

${ \cot^{2} ( \alpha ) } = \frac{49}{64}$

SO YOUR ANSWER OF COT SQUARE THETA IS 49 / 64.
