If p:q = 3/4:2 and p:r = 1/3: 1/2

p : q : r = 1 : 8/3 : 3/2

Step-by-step explanation:

p/q = (3/4)/2 = 3/(4*2) = 3/8

=> q = (8/3)p

p/r = (1/3)/(1/2) = (1*2)/(3*1) = 2/3

=> r = (3/2)p

=> (p, q ,r) = (p, (8/3)p, (3/2)p)

=> p : q : r = 1 : 8/3 : 3/2

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

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.
