triangle abc is similar to triangle def . the length of ac is 12 cm. the length of bc is 18 cm. the length of df is 10 cm.

what is the length of ef?

Triangle ABC is similar to triangle DEF. So, the length of the side EF is 15 cm and this can be determined by using the properties of similar triangle.

Given :

It is given that the triangle ABC and triangle DEF are similar. Therefore, the ratios of corresponding sides are also equal.

Now, substitute the values of AC, DF, and BC in the above equation.

EF = 15 cm.

So, the length of the side EF is 15 cm.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
