Triangle ABC is similar to Triangle FGH. What is the value of x in centimeters?
EleoNora [17]

<u>Given</u>:

Given that the triangle ABC is similar to triangle FGH.

We need to determine the value of x.

<u>Value of x:</u>

Since, the triangles are similar, then their sides are proportional.

Thus, we have;

\frac{AC}{FH}=\frac{AB}{GF}=\frac{BC}{GH}

Let us consider the proportion \frac{AB}{GF}=\frac{BC}{GH} to determine the value of x.

Substituting AB = 9 cm, GF = 13.5 cm, BC = 15 cm and GH = x, we get;

\frac{9}{13.5}=\frac{15}{x}

Cross multiplying, we get;

9x=15 \times 13.5

9x=202.5

 x=22.5 \ cm

Thus, the value of x is 22.5 cm

Hence, Option F is the correct answer.

-7x-2y=-13<br> x-2y=11<br><br><br> ***PLS SHOW STEPS***
tino4ka555 [31]

Answer:

Step-by-step explanation:

-7x-2y=-13

x-2y=11

(subtract the first inequality from the second)

-7x-x = -8x

-2y-(-2y) = 0

-13-11= -24

-8x=-24

x=3

(now place the x value into the second inequality)

3-2y=11

-2y=11-3

-2y=8

y=-4

x=3

y=-4
