Answer:
x represents the number of shirts he bought
We know that
if <span>QT is an altitude of triangle QRS
then
</span><span>the measure of angle QTS is equal to 90</span>°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13
the answer is
QR=13
Answer:

Step-by-step explanation:
The given equation is :

Where
s is displacement
u is the initial velocity
a is acceleration
t is time
If u = 0, the above equation become,

Hence, the value of t is equal to
.
