The constants in this expression are:
B.) -3 and 2/3
That would be option B.
wriiten as below
x^2 + y^2 = 42
- the 42 = the square of the radius of the circle.
Using trigonometric ratios, the measure of side n to one decimal is 6.6 units.
<h3>How to solve for a side using trigonometric ratios?</h3>
Using the trigonometric principle
SOHCAHTOA,
cos 20 = adjacent / hypotenuse
adjacent side = n
hypotenuse side = 7
Therefore,
cos 20° = n / 7
cross multiply
n = 7 cos 20°
n = 7 × 0.93969262078
n = 6.5778483455
n = 6.6 units

From the segment addition postulate with respect to line segment DG, we have that; x = 7
<h3>How to use the segment addition postulate?</h3>
The segment addition postulate states that if "B" is between "A" and "C", then the length of segment "A" "B" + the length of segment "B" "C" equals the length of segment "A" "C."
AB + BC = AC
Applying the segment addition postulate to line segment DG, gives us;
DO + OG = DG
Thus;
4x - 3 + 2x + 21 = 60
6x + 18 = 60
6x = 60 - 18
6x = 42
x = 42/6
x = 7

Hi there!
To solve this problem, we need to simplify.
15 + w - 12 = 15 - 12 + w
3 + w = 3 + w
w = w
So, the answer is undefined, since w is not given.
Hope this helps!
