The length of a rectangle is 2 feet more than 5 its width. The perimeter is 52 feet. Find the dimension of the rectangle
Ber [7]

Answer: The length is 22 feet. The width is 4 feet.

Step-by-step explanation: Create an equation for the length: 2+5w=52.

Now combine the two sides to get 4+10w=52. Plug in some numbers that seem reasonable. I started with 4, checked my work and found that it was right. This problem is all about trial and error.

So, 4+10(4)= 44. Make sure to remember the width, so add 4 for each side: 44+8. 44+8=52. Hope this helps :)

What is cot(&lt; a)?<br>Reduce fractional answers to lowest terms.​
jeka94

Answer:

The value of cot (∠A) = 3/4

Step-by-step explanation:

Given the angle ∠A of a right-angled triangle

  • The opposite of ∠A = 4
  • The adjacent of ∠A = 3

We know that the trigonometric ratio

cot (∠A) = adjacent / opposite

             =  3/4

Thus, the value of cot (∠A) = 3/4
