Question

Calculate the length of EF, one of the horizontal edges of block
The length of EF = ______

Answer 1

Answer:

the length deponds uponds magnitude of ef

Answer 2

Answer:

The length of EF is 15cm.

Step-by-step explanation:

• A triangle is defined as the three-sides of the polygon that will have three vertices.
• They are seen to be connected with each other at one end point. They have three angles other triangle which will be equal to 180°.

Given that:

The one of the horizontal edges of block.

To find:

The length of EF =?

Solution:

Let us consider two triangles,

The first triangle has a length of 12cm and 18 cm.

The second triangle has a length of 10cm.

Now, we know that,

When the triangles are similar it will from a ratios that are equal.

Let us take,

$\frac{AC}{DF}$ = $\frac{AB}{DE}$ =$\frac{CB}{EF}$

Now, we know that,

AC = 12

DF = 10

CB= 18

According to the equation, we can subsitiute the values, we get,

$\frac{12}{10}$ = $\frac{AB}{DE}$= $\frac{18}{EF}$

No, we will consider the first and third equation, we get

$\frac{12}{10}$ = $\frac{18}{EF}$

Therefore,

$12*EF$= $10*18$

$EF$ = $\frac{180}{12}$

$EF =15$

Therefore, the length of EF is $15 cm.$

Hence, proved.
