Answer:
what is the perimeter of a 12 cm and 4cm is16cm
Bracket expansion or simplifying
(8/-4) / (-3/9)=
(8/-4) * (9/3)=
72/-12=
-6
10x+2x+13=145
angle of WIJ and HIW is equal to 145 degrees
12x+13=145
12x=132
x=11
angle of WIJ is 10x
angle of HIW is 2x+13
to find angle of HIW, you plug in x=11 into 2x+13 and
the answer and angle of HIW is 35 degrees.
