Remark
If the lines are parallel then triangle RQS will be similar to triangle RTP
From that, all three lines in one triangle will bear the same ratio to all three lines of the second triangle.
Givens
PQ = 8
QR = 5
RS = 15
ST = x + 3
Ratio
QR/RP = RS/RT
Sub and solve
RP = 5 + 8
RP = 13
RT = 15 + x + 3
RT = 18 + x
5/13 = 15 / (18 + x) Cross multiply
5(18 + x) = 195 Remove the brackets on the left.
90 + 5x = 195 Subtract 90 from both sides.
5x = 105 Divide by 5
x = 105/5

C it’s what I chose for it
Answer:
i dont know
Step-by-step explanation:
that is too hard
Answer:
D
Step-by-step explanation:
if you multiply 5 by 2 you get 10
if you multiply 6 by 2 you get 12
5/2 (2) =10/12
Hope this helped

D. because when u take the square roots it's not a solid number it's a decimal
