In the diagram below of triangle PQR, S is the midpoint of PR and T is the midpoint of QR. If ST = 6x – 11, and PQ = -8x + 38, what is the measure of
ST?

what is the original number? you forgot to add it.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
