Answer:
the answer is x=15 cm
Step-by-step explanation:
here the above given figure is a rectangle ABCD with diagonals AC and BD measuring AC= (x+10)cm and BD=(3x-20) cm
Now,
AC=BD
or, 3x-20 = x+10 [ diagonals of a rectangle are equal]
or, 2x = 30
or, x= 15 cm

In a meter there are 100 cm.
In 100 cm there are 1000 mm.
Therefore in 1 meter you have 1000 millimeters.
Then to find out how many millimeters you have in 14 meters, you just multiply 14 by 1000 to give you 14000 mm.
Final answer= 14 m of gold wire is the equivalent to 14000 mm of wire.
Use the Pythagorean theorem: a² + b² = c²
c = hypotenuse (which means) = 53
a and b are equal to the side length
So a = 21.
Use the formula and solve.
21² + b² = 53²
441 + b² = 2809
b² = 2368
b = 48.66210024238575 or 8√37
