<h3>What is a triangle?</h3>A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.
A.) The value of n can be found by equating XY and XZ together,
XY = XZ
9n + 12 = 15n - 6
12 + 6 = 15n - 9n
18 = 6n
n = 3
Hence, the value of n is 3.
The length of different legs of the triangle is,
B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39
C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39
Hence, the length of the legs XY and YZ is equal to 39 units.

Answer:
The surface area of the gift box is =
Step-by-step explanation:
The surface area of the cylinder can be calculated using this formula:
in this case, r is not a number, but rather an expression, which is r = .
The height of the gift box is twice the radius, which is h =
To get our curved surface area, we carefully put the expressions for h and r into the equation.
The surface area of the gift box is =
