Answer:
X=1 m
X= 0.81 m
Explanation:
for the first X you must put in a proportion like this
38:8=4:X
X=(4×8)/38= 1 m
for the second one's you could use Pythagorean theorema
finding the diagonal of the biggest rectangle and you must put the diagonals in proportion whit the 2 sides
32:4=Y:32.9
Y=(32×32.9)/4=4.1 m (diagonal of the smallest rectangle)
use an other time the Pythagorean theorema and you find the other option
