Find the value of cosine for angle a

I believe the answer is 8/√89. Hope this helps.

 The cosine of angle A is

Step-by-step explanation:  We are given to find the value of cosine for angle A from the figure.

From the figure, we see that

triangle ABC is a right-angled triangle with ∠C = 90° and hypotenuse AB.

Also, AB = 8 ft and BC = 5 ft.

Using Pythagoras theorem in right-angled triangle ABC, we have

Therefore, we get

Thus, the cosine of angle A is

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
