A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72
b=4a+c
b=4(18)+36
b=72+36
b=108
Wow matrixes gg
a)[ 1 1 4 ]
[-7 -6 -1 ]
[ 0 4 0 ]
b)[ 15 12 12 ]
[-12 -12 0 ]
[3 6 0 ]
c)[ 7 4 12 ]
[ -18 -16 -2 ]
[ 1 10 0 ]
d) I forgot how to do d lol so heres all I got.
