OLEGan [10]

It is given in the question that

A farmer owns about 960 acres of land. If his farm is square.

First we convert acres to miles square, and the conversion expression is

1 acre=0.0015625 mi^2

Therefore,

960acres=960*0.0015625=1.5 mi^2

Let the side length of the square be x miles .

And the formula of area of square is

Area=side^2
\\
1.5=side^2
\\
side= \sqrt{1.5}=1.2 miles

Sin A 7 divided by 25
Brums [2.3K]

Answer:

Cos A = 24/25, Tan A = 7/25

Step-by-step explanation:

Given that Sin A = 7/25

Sin = Opp/hyp

Therefore using Pythagoras theorem, adjacent will be;

= √(25²-7²)

= √576

= 24

Thus;

Cos A = adjacent/hypotenuse

          =  24/25

Cos A = 24/25

Tan A = opp/hypotenuse

         = 7/25

Tan A = 7/25
