If T is the midpoint of SU find the values of x, ST and SU.

Nitella [24]

Answer: The required values are

x = 12 units, ST = 60 units and SU = 120 units.

Step-by-step explanation: Given that T is the midpoint of SU, where

ST = 5x and TU = 3x + 24.

We are to find the values of x, ST and SU.

Since T is the midpoint of SU, so we get

$ST=TU\\\\\Rightarrow 5x=3x+24\\\\\Rightarrow 5x-3x=24\\\\\Rightarrow 2x=24\\\\\Rightarrow x=\dfrac{24}{2}\\\\\Rightarrow x=12.$

So, the value of x is 12.

Therefore,

$ST=5\times12=60$

and

$SU=5x+3x+24=8x+24=8\times12+24=96+24=120.$

Thus, the required values are

x = 12 units, ST = 60 units and SU = 120 units.
