If triangle STR ~ triangle PTQ, find QT
lana [24]

Answer:

QT = 45

Step-by-step explanation:

ST = 65

SP = 26

RQ = 30

QT = 4x - 3

Given that ∆STR is similar to ∆PTQ, therefore:

\frac{ST}{PT} = \frac{RT}{QT}

Plug in the values

\frac{65}{65 - 26} = \frac{30 + (4x - 3)}{4x - 3}

Solve for x

\frac{65}{39} = \frac{30 + 4x - 3)}{4x - 3}

\frac{5}{3} = \frac{27 + 4x}{4x - 3}

Cross multiply

5(4x - 3) = 3(27 + 4x)

20x - 15 = 81 + 12x

Collect like terms

20x - 12x = 81 + 15

8x = 96

Divide both sides by 8

x = \frac{96}{8}

x = 12

✅QT = 4x - 3

Plug in the value of x

QT = 4(12) - 3 = 48 - 3

QT = 45
