Angle x and angle y are complementary angles if angle y is 5 times the size of angle x .what is the value of x and y
Ivahew [28]

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

Find the
Mazyrski [523]

Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = \frac{s^2\sqrt{3} }{4}  ( s is the side length ) then

\frac{s^2\sqrt{3} }{4} = 81\sqrt{3} ( multiply both sides by 4 to clear the fraction )

s²\sqrt{3} = 324\sqrt{3} ( divide both sides by \sqrt{3} )

s² = 324 ( take the square root of both sides )

s = \sqrt{324} = 18

Thus

perimeter = 3 × 18 = 54 cm
