Answer:
Step-by-step explanation:
x^2 - 8x + 16 = (x - 4)^2
the first one
-----------------------------------------------
Define x :
-----------------------------------------------
Let the smallest number be x.
The other two numbers will be x+1 and x+2.
-----------------------------------------------
Construct equation :
-----------------------------------------------
The sum of all 3 numbers is 78
⇒ x + x + 1 + x + 2 = 78
-----------------------------------------------
Solve x :
-----------------------------------------------
x + x + 1 + x + 2 = 78
3x + 3 = 78
3x = 78 - 3
3x = 75
x = 25
-----------------------------------------------
Answer: Smallest number = 25
-----------------------------------------------
A^2+b^2= c^2
16^2+ 28^2= c^2
square root of 256+784 = square root of 1,040
32.25=32.25
C= 32.25
Answer:
x = 93
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x - 73 + x + 67 = 180
2x - 6 = 180 ( add 6 to both sides )
2x = 186 ( divide both sides by 2 )
x = 93
912.501 is your answer. :)
