The values of x and y are 15 and 75, respectively
<h3>How to determine the values of x and y?</h3>
The statements are given as:
- Angle x and angle y are complementary angles
- Angle y is 5 times the size of angle x
These mean that
x + y = 90
y = 5x
Substitute y = 5x in x + y = 90
x + 5x = 90
Evaluate the sum
6x = 90
Divide by 6
x = 15
Substitute x = 15 in y = 5x
y = 5 *15
Evaluate
y = 75
Hence, the values of x and y are 15 and 75, respectively

Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A = 
( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s² = 324 ( divide both sides by )
s² = 324 ( take the square root of both sides )
s = 
= 18
Thus
perimeter = 3 × 18 = 54 cm
