Question

please solve this question 17 no please it's urgent

Answer 1

cos@ = 3/5 = b/h

$sinx = \sqrt{1 - {cos}^{2}x }$
sin@ = √(1 - (3/5)^2)
so sin@ = 4/5


perpendicular = p = 4

base = b = 3

hypotenuse = h = 5

cot@ = b/p = 3/4

tan@ = 4/3
filling values
we get
$\frac{ \frac{ 4}{5} - \frac{3}{4} }{2( \frac{4}{3}) }$
(1/20)
____
(8/3)

it becomes

3/160. answer
