Answer:
Option B.
Step-by-step explanation:
It is given that ΔSRQ is a right angle triangle, ∠SRQ is right angle.
RT is altitude on side SQ, ST=9, TQ=16 and SR=x.
In ΔSRQ and ΔSTR,
(Reflexive property)
(Right angle)
By AA property of similarity,
Corresponding parts of similar triangles are proportional.
Substitute the given values.
On cross multiplication we get
Taking square root on both sides.
The value of x is 15. Therefore, the correct option is B.

Step-by-step explanation:
so a proportional relationship does not have y-intercepts (ex.: starting price...)
<em>"a small pizza costs $9 and each additional topping costs $.75"</em> is not proportional because it does not start at 0.
<em>"a student earns $12 for each hour she tutors"</em> for example, is proportional because it does start at 0 and does not have anything added to it.
<u>proportional: y = mx</u>
<u>not proportional: y = mx + b</u>
x² - x - 12 ≠ 0
x² - 4x + 3x - 12 ≠ 0
x (x - 4) + 3 (x - 4) ≠ 0
(x + 3)(x - 4) ≠ 0
x ≠ -3 or x ≠ 4
