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:
(8x-7)(8x+7)
Step-by-step explanation:
This is a difference of squares polynomial of the form  . Since 64 and 9 are both perfect squares then take the square root of each so a=8 and b=7.
. Since 64 and 9 are both perfect squares then take the square root of each so a=8 and b=7.

<span>cylindrical vase
r=radius </span>cylinder=radius cone
h= height cylinder=height cone
Volume  cylindrical vase (V1)= 63 cm³=pi*r² *h
cone
Volume cone (V2)=pi*r² *h
if radius cylinder=radius cone  and height cylinder=height cone
then V1=V2
therefore
V2= 63 cm³
the answer is The volume of cone is 63 cm³
