Solve using Triangle proportionality theorem

Solve using Triangle proportionality theorem

Solution

The diagram in the image involves parallel lines and can be solved using the Triangle Proportionality Theorem, also known as the Basic Proportionality Theorem. This theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, it divides those two sides proportionally.

Key Elements:

  • WUWU is the full length (35).
  • VTVT is the length on the parallel lines (24).
  • WSWS is the other part, given as 22.

We want to find TUTU, which is the missing part of line segment WUWU.

Steps:

Using the Triangle Proportionality Theorem:

TVTU=WSWU\frac{TV}{TU} = \frac{WS}{WU}

Substitute the values we know:

24TU=2235\frac{24}{TU} = \frac{22}{35}

Now solve for TUTU:

2435=22TU24 \cdot 35 = 22 \cdot TU

840=22TU840 = 22 \cdot TU

TU=84022=38.18(rounded to two decimal places)TU = \frac{840}{22} = 38.18 \, (\text{rounded to two decimal places})

Final Answer:

TU38.18TU \approx 38.18
