Hello and Good Morning/Afternoon:
<u>Let's take this problem step-by-step</u>:
<u>What does the information want:</u>
<u>Let's gather some information</u>:
- ΔA'BC' and ΔABC are similar triangles
⇒ Angle B is shared by both triangles
⇒ Angle A' and A are the same, as they are both on parallel
lines, A'C' and AC, and both angles are formed with the
same line AB
⇒ by the <em>Angle-Angle Theorem*</em>, they are similar triangles
<u>If they are similar triangles</u>:
⇒ their side lengths are proportional to each other
⇒ let's set up a proportion
⇒ let's set up a proportion
<u>Answer:</u>
- <u>x= 17.143</u>
- <u>y = 26.25</u>
Hope that helps!

Answer:
x = 4.25
Step-by-step explanation:
1. distribue the -5 on the left side of the equal sign by multiplying it with 2x and -9 inside the brackets. Do the same with the negative sign and the -6x and 10 in the brackets on the right side of the equation. this should make:
17 - 10x + 45 = 6x - 10 + 4
2. Combine like terms on both sides of the equal sign. Add 17 and 45, and add -10 and 4 to make:
62 - 10x = 6x - 6
3. Bring like terms onto the same side. You can either bring the 62 to -6, which would make 62 negative, or bring -6 to 62, making the 6 positive. Do the same with -10x and 6x. It should make:
68 = 16x OR -68 = -16x
4. Divide both sides by 16 or -16, depending on which option you went with.
68/16 = 16x/16 OR -68/-16 = -16x/-16
This gives:
4.25 = x
Substitute into
Insert y = 5 into
