Answer:
x = 105
Step-by-step explanation:
the sum of all interior angles of any four-sided figure has 360 degrees
∡F and ∡H are equal
add all four expressions and set them equal to 360
x + (x + 5) +( x + 5) + (140 - x) = 360
combine like terms
2x + 150 = 360
2x = 210
x = 105

Answer:
8
Step-by-step explanation:
Even though we don't know the number yet, let's name this number "n".
8n + 3 = 6n + 19
8n + 3 - 6n = 6n + 19 - 6n
2n + 3 = 19
2n = 16
n = 16/2
n = 8
Our number is 8.
Note: This answer is 100% correct.
