552 = 502 + 352 − 2(50)(35)cos(A) After working through the problem above, we get cos(A) = .

We have been given an equation . We are asked to find the values of .

First of all, we will square the terms.

Now we will subtract 3725 from both sides as:

Switch sides:

Upon dividing both sides by , we will get:

Therefore, the values of is 0.2.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
