Y=29
x+y+78=180
x+29+78=180
x=180-78-29
x=73
z=180-73
z=107
x=73 degrees
y=28 degrees
z=107 degrees
Answer:
The final degree is 90
Step-by-step explanation:
Because every triangle equals up to 180 degrees.
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.
