The answer is the first one A. sss Postulate
Answer:
40
Step-by-step explanation:
5+1 3/8n=60
Subtract 5
1 3/8n=55
11/8n=55
8/11(55/1)
n=40
For
ax+by=c
slope=-a/b
perpendiculare lines have slopes that multiply to -1
so
2x+3y=9
slope=-2/3
-2/3 times what=-1
what=3/2
point slope form
the equation of a line that passes through the point (x1,y1) and the slope is m is
y-y1=m(x-x1)
slope=3/2
point i (8,5)
equation is
y-5=3/2(x-8)
converted to standard form
2y-10=3x-24
-3x+2y=-14
3x-2y=14
