Answer:
x = 20
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= ( cross- multiply )
9x = 180 ( divide both sides by 9 )
x = 20
Answer:
y-9 = -2x
Step-by-step explanation:
The point slope form of a line is given by
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is the point
y-9 = -2(x-0)
y-9 = -2x
Answer:
Step-by-step explanation:
It is given that the length of triangle base is 26, then let ABC be the triangle and BC be the base of the triangle=26.Let DE be the parallel line to the base that divides triangle ABC into two equal area parts.
Now, Let AD=a, DB=b, DE=c, AE=d and EC=e, then
Since, triangle ABC is similar to triangle ADE, thus using basic proportions, we get
Taking the first two equalities,we get
Thus, the length of the segment between triangle legs is

Answer:
The estimated taken to drive downtown using App is 38.4 minutes
Step-by-step explanation:
Given as :
The initial time taken to drive downtown = i = 48 minutes
The percentage error of time = r = 20%
Let The estimated time using app = t min
Let the time = 1 min
<u>Now, according to question</u>
The estimated time using app = The initial time taken to drive downtown ×
Or, t minutes = i minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
∴ t = minutes
I.e t = 38.4 minutes
Or, The estimated time using app = t = 38.4 min
Hence, The estimated taken to drive downtown using App is 38.4 minutes Answer
