Answer:
The scale factor is 2.
Step-by-step explanation:
Divide 2 by 1 then you get 2. I got the 2 and the one from the shapes. So don’t get confused ;)
Answer:
x=6
Step-by-step explanation:
4x-1=2x+11
4x-2x-1=11
2x-1=11
2x=11+1
2x=12
x=12/2
x=6
Answer:
C= 10.6
Step-by-step explanation:
AB^2=AC^2+CB^2
C^2=7^2+8^2
C^2= 113
√113=10.630
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°
