Question

Find the value of the variabels and the side lengths

Answer 1

adjacent lengths are given to be equal
2x+5 = x+12
can you find x from here ?

Answer 2

x=7?

Answer 3

yes! good :)
now from y-4 = x+5
you will also get value of y :)

Answer 4

Since the sides are equal
We know that
2x + 5 = x + 12 and y -4 = x+ 5

Using the first equation solve for x
Subtracting x from both sides and subtracting 5 from both sides
x = 7

Now using x = 7 in the 2nd equation
y - 4 = 7 + 5 = 12
so adding 4 to both sides
y = 16

so the sides are 19, 19 ,12, 12

Answer 5

Thanks @VAlb That makes a lot of sense... if you could check out my other question that would be great
