Question

If RT is 10 centimeters long, what is ST?

Answer 1

The answer is 6 centimeters

Answer 2

Answer:

6 centimeters

Step-by-step explanation:

Given : Length of RT is 10 centimeters .

           Length of RS is 2x centimeters .

           Length of ST is 3x centimeters .

To Find : Length of ST .

Solution :

$RS = 2x$

$ST=3x$

$RT = 10$

Refer the given figure

we can see that RS +ST = RT

⇒$2x+3x=10$

⇒$5x=10$

⇒$x=\frac{10}{5}$

⇒$x=2$

Thus the value of x is 2

And we are given RS = 2x and ST = 3x

⇒$RS = 2x = 2*2 = 4 cms$

⇒$ST = 3x = 3*2 = 6 cms$

Hence , The length of ST is 6 centimeters.
