Here , the ratio UV:VW and UT:TS will be in proportion , so ;

${:\implies \quad \sf \dfrac{UV}{VW}=\dfrac{UT}{TS}}$

Putting the given values ;

${:\implies \quad \sf \dfrac{18}{36}=\dfrac{UT}{24}}$

${:\implies \quad \sf UT=\dfrac{1}{2}\times 24}$

${:\implies \quad \bf \therefore \quad \underline{\underline{UT=12 \:\: units}}}$

Hello!

Distance between two points (2,9) and (6,3) -

1. Take the Absolute Difference between the X points 2 and 6. The Absolute Difference is 4. 
2. Square 4 = 16 
3. Take the Absolute Difference between the Y points 9 and 3. The absolute Difference is 12. 
4. Square 12 = 144 
5 Add 144 + 16 = 160 
6. Take the Square root of 160

3) y^2 - 1 = 24

add 1 to each side:

y^2 = 25

Take square root of each side: y = √25

y = 5 or -5

4) y^2 - 1 =48

Add 1 to each side:

y^2 = 49

Take square root of each side:

y = 7 or -7
