Answer:
an = a(n-1) +5
Step-by-step explanation:
The value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9
<h3>Trigonometry </h3>
From the question, we are to determine the values of the missing sides
From the diagram,
Opposite = 9
Adjacent = y
Hypotenuse = x
Included angle = 45°
Using SOH CAH TOA, we can write that
∴ y = 9
Since the triangle is a right triangle, we can write that
x² = y² + 9² (<em>Pythagorean theorem</em>)
x² = 9² + 9²
x² = 81 + 81
x² = 162
x = √162
x = 12.7
Hence, the value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9

Answer:
17.98 square meters
Step-by-step explanation:
find the area of rectangle
length x width
6.2x1.8= 11.16
find area of triangle
base x height x 1/2
base= 6.2
height= 4-1.8= 2.2
area=2.2 x 6.2 x 1/2 = 6.82
add both together to get area of figure
6.82 + 11.16 = 17.98
If you know that y = 6. You just have to switch Y by 6.
x + 2y = 16
x + 2*6 = 16
x + 12 = 16
x = 16 - 12
x= 4
4 + 2*6 = 16
Hope this helps !

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol. See: Variable.
