$\cos(60) = \frac{12}{x} \\$

$\frac{1}{2} = \frac{12}{x} \\$

$x = 24$

_____________________________________________

$\sin(60) = \frac{y}{x} \\$

$\frac{ \sqrt{3} }{2} = \frac{y}{24} \\$

$y = 12 \sqrt{3}$

There is a Multiplication in the brackets    7 x 3

For the answer
(9 - 7 x 3 + 4)²
Brackets
Multiplication   7 x 3 = 21
(9 - 21 + 4)²
Addition   -21 + 4 = -17
(9 - 17)²
Subtraction    9 - 17 = -8
-8²

Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64
