If PQR ~ SQT, find the value of x

Given:

Given that the triangle PQR is similar to SQT.

The length of PS is (x + 5)

The length of SQ is 8.

The length of ST is (x - 9)

The length of PR is 21.

We need to determine the value of x.

Value of x:

Using the similar triangles property, we shall determine the value of x.

Hence, we have;

Substituting the values, we get;

Cross multiplying, we get;

The value of x can be determined using the quadratic formula.

Thus, we have;

Since, x cannot take negative values, then x = 16.

Hence, the value of x is 16.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
