Answer:

<u>LENGTH OF AC IS 6</u>

Step-by-step explanation:

Given :

<em>the side AC = x ;</em>

we need to find x;

<em>since ∠A = ∠C , It's an isosceles triangle . i.e ,</em>

<em>the sides opposite to the angles ( AB and CB ) are also equal.</em>

thus ,

side

AB = x+4 ;

CB = 3x-8 ;

thus AB = CB or ,

x+4 = 3x-8 ,

2x = 12 ,

x = 6 ;

<u>therefore the side AC is 6.</u>

How do you find the slope of a line perpendicular to a given line?
enyata [817]
You have a line:
y=mx+b  (slope-intercepted form)
m=slope of this line.

The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.

For example:
y=8x+3
m=8

The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8

Reliable taxis : for 30 miles
C = 1.5x....x = 30
C = 1.5(30)
C = 45

speedy taxis : for 30 miles
C = 1.1x + 11.5....x = 30
C = 1.1(30) + 11.5
C = 33 + 11.5
C = 44.5

city taxis : for 30 miles
C = 1.25x + 8...x = 30
C = 1.25(30) + 8
C = 37.5 + 8
C = 45.5
