Answer:
X=6
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x-5+3x=7x+1
8x-5=7x+1
8x-7x=1+5
So the answer is X=6
so the smallest angle is angle A which is 30 degree
a,e,f
a. 6p+6
b.12p
c.6p
d.5p+6
e.6p+6
f.6p+6
D 12rad2 12rad2 24
1) 4 + 3(x) = 19
3x=15
x=5
2) 2x -7 = 9
2x=16
x=8
3) not sure
4) 5 (x + 4) = -15
5x+20=-15
5x=-35
x=-7
