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?

Step-by-step explanation:

You know that the triangle ABC and the triangle DEF are similar.

Therefore, if the lenght of AC is 12 centimeters and the lenght of DF is 10 centimeters, then you can find the ratio as following:

Then, the calculte the length of EF, you must multiply the lenght BC of the triangle ABC by the ratio obtained above.

Therefore, the lenght EF is the following:

The length of EF = 15 cm.

Step-by-step explanation:

We are given that the two triangles, ABC and DEF, are similar to each other,

Given that the length of AC = 12 cm, BC = 18 cm and DF = 10 cm, we are to find the length of EF.

For this, we can simply use the ratio method.

EF = 15 cm

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
