My answer I got 9x13and half over 1=x
By using the concepts of <em>unit</em> circle and <em>trigonometric</em> functions, we find that the angle OA, whose x-coordinate is 0.222, has a measure of approximately 77.173°.
<h3>How to find an angle in an unit circle</h3>
<em>Unit</em> circles are circles with radius of 1 and centered at the origin of a Cartesian plane, which are used to determine angles and <em>trigonometric</em> functions related to them. If we use <em>rectangular</em> coordinate system and the definition of the <em>tangent</em> function, we find that the angle OA is equal to:


tan θ ≈ 77.173°

Answer:
6 meters
Step-by-step explanation:
if his length is 9 multiply it by two so u have 18 and then subtact its from 30 so u have 12 and divide that by 2 so now u have 6
2x² - 5xy - y³
x = -3 and y = -2
2.(-3)² - 5.(-3).(-2) - (-2)³
2.9 + 15.(-2) - (-8)
18 - 30 + 8
26 - 30
-4
