Answer 1

Step-by-step explanation:

Here comes the answer

Basic Use of alegbraic expression like

Answer 2

this is in the form of

(a+b) (a+b) = a square - b square

= (1 square - sinQ square)/

(1 square - cos q square)

= 1- sin square / 1 - cos q square

=sin q square/ cos q square

=1/ tan square = 8/7^2 = 64/49
