Answer:
-5
Step-by-step explanation:
y- 1/5x = 7
y= 1/5x +7
So, the slope of the line is 1/5
Perpendicular slopes are always the reciprocal with an inverse sign.
So, -5
Step-by-step explanation:
sum of four angles=360°
a=128
b=126
c=54
d=?,let d=x
128+126+54+x=360°
308+x=360
find like terms
x=360-308
x=52°
Set it up like this:

. Then you would cross multiply which would result in:

. Divide by 9 on both sides and

.
Area formula is = lx b
Whete we lnow area and width so
We can easily find out length
20.5 = 2.5 × l
l = 20.5 / 2.5
Length = 8.2 cm answer
