either

-(3x+3)-2x (less than) -4(x-2)-2

-3x+3-2x (less than) -4x +8-2

-5x+3 (less than)-4x+6

Or if you need it simplified

-5x +3 (less than) -4x+6

+4x 4x

-x+3 (less than) 6

-3 -3

-x(less than) 3

(-x/-1) Less than (3/-1)

x (less than) -3

(didnt have the less than greater than sign so typed it)

How do you solve this

Dmitriy789 [7]

By definition of the trig functions,

$\sin30^\circ=\dfrac y{16}$

$\cos30^\circ=\dfrac x{16}$

We have $\sin30^\circ=\dfrac12$ , so $y=8$ , and $\cos30^\circ=\dfrac{\sqrt3}2$ , so $x=8\sqrt3$ .

Just to check: we should have

$x^2+y^2=16^2$

by the Pythagorean theorem. Indeed,

$8^2+(8\sqrt3)^2=4\cdot8^2=2^2(2^3)^2=2^8=(2^4)^2=16^2$
