Answer:

x = 15\sqrt{3} , y = 15

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and the exact values

sin60° = \frac{\sqrt{3} }{2} , cos60° = \frac{1}{2} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{x}{30} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 30\sqrt{3} ( divide both sides by 2 )

x = 15\sqrt{3}

---------------------------------------------------------

cos60° = \frac{adjacent}{hypotenuse} = \frac{y}{30} = \frac{1}{2} ( cross- multiply )

2y = 30 ( divide both sides by 2 )

y = 15

Spencer has a rectangular garden. The length and width are both odd numbers and the perimeter is 16 feet. What can be the area o
vovikov84 [41]

Area of rectangle = length x width

Perimeter of rectangle = 2 x (length + width)

Now we know that perimeter of rectangle = 16

2(length + width) = 16

Length + width = 16/2

Length + width = 8

Now the value of length and width is that if we add both values we have the answer 8.

So, here are some possible values of length and width and also that length and width are odd numbers;

Odd numbers are = 1,3,5,7,….

7 + 1 = 8

5 + 3 = 8

So, either length is 7 and with is 1 or length is 5 and width is 3

So area of rectangle = 7 x 1 = 7 or 5 x 3 = 15

Thus, the possible values of area of rectangle are 7 ft² and 15 ft².
