Answer 1

Here, we have two pairs of similar triangles.

Let's find the values of x and y.

• Sol,vin,g for x:

Given:

Length of longer base = 9

Length of shorter base = 5

Length of smaller leg = 8

Let's solve for x.

Since the triangles are similar, the corresponding sides will be in proportion.

To solve for x, apply the proportionality equation:

`(9)/(x)=(6)/(8)`

Cross multiply and solve for x:

`\begin{gathered} 6x=9*8 \\ \\ 6x=72 \\ \\ \text{ Divide both sides by 6:} \\ (6x)/(6)=(72)/(6) \\ \\ x=12 \end{gathered}`

• Solving for y:

Given:

Length of longer base = 3

Length of longer leg = 6

Length of smaller leg = 4

Length of total base = y

To solve for y, we have the equation:

`(6)/(3)=(4)/(y-3)`

Cross multiply and solve for y:

`\begin{gathered} 6(y-3)=4*3 \\ \\ 6y-6(3)=12 \\ \\ 6y-18=12 \\ \\ \text{ Add 18 to both sides:} \\ 6y-18+18=12+18 \\ \\ 6y=30 \\ \\ \text{ Divide both sides by 6:} \\ (6y)/(6)=(30)/(6) \\ \\ y=5 \end{gathered}`

ANSWER:

• x = 12

• y = 5
