Answer:

AB = [tex]\frac{108}{7}[/tex]

Step-by-step explanation:

Δ ALM and Δ ACB are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{AM}{AB}[/tex] = [tex]\frac{AL}{AC}[/tex] , substitute values

[tex]\frac{12}{AB}[/tex] = [tex]\frac{14}{18}[/tex] = [tex]\frac{7}{9}[/tex] ( cross- multiply )

7AB = 108 ( divide both sides by 7 )

AB = [tex]\frac{108}{7}[/tex] ( = 15 [tex]\frac{3}{7}[/tex] )

Which equation has both 3 and -3 as possible values of y ?

Answers

Answer:

[tex] {y}^{2} - 9 = 0[/tex]

Step-by-step explanation:

as both 3 and - 3 are possible values of y;

[tex]y = 3 \: or \: y = - 3[/tex]

[tex]y - 3 = 0 \: or \: y + 3 = 0[/tex]

therefore;

[tex](y - 3)(y + 3) = 0[/tex]

by expanding;

[tex] {y}^{2} - {3}^{2} = 0[/tex]

[tex] {y }^{2} - 9 = 0[/tex]

(PLEASE) Triangle IJK is similar to triangle LMN. Find the measure of side MN. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale.

Answers

Answer:

MN = 126.31

Step-by-step explanation:

ΔIJK = ΔLMN --- (given)

So,-----------------------

KI / KJ = NL / MN

19 / 40 = 60 / MN

MN = 60 × 40 / 19

MN = 126.31

The required measure of side MN will be 126.3 units.

What are Similar Triangles?

Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.

Given that triangle ΔIJK ~ ΔLMN in the question.

We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.

As per the similarity rule of triangles, we can write the ratio as:

⇒ KI / KJ = NL / MN

⇒ 19 / 40 = 60 / MN

⇒ MN = 60 × 40 / 19

⇒ MN = 126.3157

Rounded to the nearest tenth to get

⇒ MN = 126.3
