Hello from MrBillDoesMath!
Answer:
75
Discussion:
A plane triangle has 180 degrees. Using this in the diagram gives
x + 81 + angle BAC = 180 (***)
(The diagram is a bit fuzzy but I think the above numbers are accurate)
The diagram also shows that (156 + angle BAC )= 180 as a straight line has 180 degrees. So
angle BAC = 180 - 156 = 24
Substituting this in (***) above gives
x + 81 + 24 = 180 =>
x + 105 = 180 => (as 81 + 24 = 105)
x = 180 107 = 75
Check: Does
x + 81 + angle BAC = 180 ?
75 + 81 + 24 = 180. Yes
Thank you,
MrB

Based on definition of <em>unit</em> circle and <em>angle</em> properties on <em>Cartesian</em> plane, we find the following results: A: π/5, B: 3π/7, C: 4π/3.
<h3>How to determine angles in a unit circle</h3>
<em>Units</em> circles are commonly used to understand angles and <em>trigonometric</em> functions in a simple way. Vectors in a <em>unit</em> circle are <em>ordered</em> pairs of <em>polar</em> form: (x, y) = (cos θ, sin θ).
To solve this problem, we must take these tips into account:
- Angles in the <em>first</em> quadrant are within 0 < θ < π/2.
- Angles in the <em>second</em> quadrant are within π/2 < θ < π.
- Angles in the <em>third</em> quadrant are within π < θ < 3π/2.
- Angles in the <em>fourth</em> quadrant are within 3π/2 < θ < 2π.
Then, we have the following results: A: π/5, B: 3π/7, C: 4π/3.
