Given:

Required:

We need to find the value of x.

Explanation:

Recall that the corresponding sides of similar triangles are proportional.

12m and 6m are corresponding sides of the given similar triangles

16m and x are corresponding sides of the given similar triangles

The proportion of the sides can be written as follows.

[tex]\frac{12}{6}=\frac{16}{x}[/tex][tex]2=\frac{16}{x}[/tex]

Use the cross-product method.

[tex]2x=16[/tex][tex]\frac{2x}{2}=\frac{16}{2}[/tex][tex]x=8m.[/tex]

2)

Given:

18cm and 30cm are corresponding sides of the given similar triangles.

x and 25 cm are corresponding sides of the given similar triangles.

Required:

We need to find the value of x.

Explanation:

Recall that the corresponding sides of similar triangles are proportional.

The proportion of the sides can be written as follows.

[tex]\frac{18}{30}=\frac{x}{25}[/tex]

Multiply both sides of the equation by 25.

[tex]\frac{18\times25}{30}=\frac{x}{25}\times25[/tex][tex]15=x[/tex][tex]x=15cm[/tex]

3)

Given:

x and 21m are the corresponding sides of the given similar triangles.

32m and 24m are the corresponding sides of the given similar triangles.

Required:

We need to find the value of x.

Explanation:

Recall that the corresponding sides of similar triangles are proportional.

The proportion of the sides can be written as follows.

[tex]\frac{x}{21}=\frac{32}{24}[/tex]

Multiply both sides of the equation by 21.

[tex]\frac{x}{21}\times21=\frac{32}{24}\times21[/tex][tex]x=28m[/tex]

4)

Given:

12in and 15in are the corresponding sides of the given similar triangles.

x and 40in are the corresponding sides of the given similar triangles.

Required:

We need to find the value of x.

Explanation:

Recall that the corresponding sides of similar triangles are proportional.

The proportion of the sides can be written as follows.

[tex]\frac{12}{15}=\frac{x}{40}[/tex]

Multiply both sides of the equation by 40.

[tex]\frac{12}{15}\times40=\frac{x}{40}\times40[/tex][tex]x=32in[/tex]

Final answer:

1)

[tex]x=8m.[/tex]

2)

[tex]x=15cm[/tex]

3)

[tex]x=28m[/tex]

4)

[tex]x=32in[/tex]
