The answer would be the first option (2.2, -1.4) it is the closest to where the two meet. Can I plz have brainliest? i need it
The plane figure formed by the ground, the guy wire, and the tree is a right triangle with the hypotenuse equal to length of the guy wire. The angle given is an angle adjacent to 3.5 ft. Therefore, the most suitable trigonometric function for this is,
cos (50°) = adjacent / hypotenuse
cos 50° = 3.5 ft / hypotenuse
The value of the hypotenuse is 5.445 ft.
Hence, the length of the guy wire is approximately 5.445 ft.
The Brady family received 1 letter on July 28.
Step-by-step explanation:
Step 1:
Assume a = the number of letters, b = the number of bills, c = the number of ads, and d = the number of magazines.
From the question, they got 15 pieces of mail that day so 
They got 5 more magazines than bills so 
The got the same number of letters as ads so 
They got 3 more bills than ads so 
Step 2:
As we have only one equation to solve the values, we need to make every term in terms of a single term.
We make everything in terms of c.
So 
Substituting all this in the equation, we get


Step 3:
Substituting c = 1 in other terms, we get


and

As a = 1, they received 1 letter that day.
