Answer:
<u>∠DFA = 82°</u>
Step-by-step explanation:
According the property of inscribed angles and arcs, the angle is half of the arc length.
Solving :
- ∠CFB = 1/2 x ∡CB
- ∠CFB = 1/2 x 164°
- ∠CFB = 82°
- ∠CFB = ∠DFA (Vertically Opposite Angles)
- <u>∠DFA = 82°</u>

Given


Required
Determine the distance between M and S
Distance (D) is calculated using:

Where








<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.

Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is

<em>i.e. we add the units to the y coordinate of P.</em>
57-10.51=46.49
46.49-8.73=37.76
37.76-8.47=29.29
Therefore Daniel has $29.29 left.
38 - 171 divided by 19 times 2
