Answer:
perimeter of Pentagon is 62 CM
perimeter of triangle is equal to 38 CM
perimeter of square is equal to 48 CM
therefore perimeter of one side of square is 48 divided by 4 is equal to 12 CM
perimeter of Pentagon is 62 CM
Answer:
32
Step-by-step explanation:
The shape in image is an equilateral triangle which means all of it's angles has equal measurements:
2x - 4 = 5y and that is equal to 60 degrees
2x - 4 = 60 add 4 to both sides
2x = 64 divide both sides by 2
x = 32

Define the two numbers
-----------------------------------------------------------
Let the first number be x.
Let the second number be y.
------------------------------------------------------------
Form equations and solve x and y
------------------------------------------------------------
x + 2y = 14 ------------------ (1)
2x + y = 31 ------------------ (2)
------------------------------------------------------------
Equation (1) x 2
------------------------------------------------------------
2x + 4y = 28 ---------------(1a)
------------------------------------------------------------
Equation (1a) - 2
------------------------------------------------------------
3y = 28 - 31
3y = -3
y = -1
------------------------------------------------------------
Substitute y = -1 into (1)
------------------------------------------------------------
x + 2(-1) = 14
x -2 = 14
x = 14 + 2
x = 16
------------------------------------------------------------
Answer: x =16, y = -1
------------------------------------------------------------
