# Math Help - hard factorise

1. ## hard factorise

hi, i need to factorise this:

would i do this:
7x=360
360/7 =51.43?

if this is wrong could you please let me know how to do it properly but IF i am right could you also let me know

2. Hello, andyboy179!

There is no factoring in this problem.

I assume we have some quadrilateral and those expressions are the four angles.

Since the angles of a quadrilateral always total $360^o$
. . . . your work is correct: . $7x\:=\:360 ^o\quad\Rightarrow\quad x \:=\:\dfrac{360^o}{7} \:=\:51\frac{3}{7}^o$

Then the four angles are:

. . $\begin{array}{cccc}3x-1 \:=\:153\frac{2}{7}^o && x+2 \:=\:53\frac{3}{7}^o \\ \\ x-4 \:=\:47\frac{3}{7}^o && 2x+3 \:=\:105\frac{6}{7}^o \end{array}$
