Answer:
6 and 7
Step-by-step explanation:
we know that 42 will lie between 36 and 49
And 36=6; 49=7
so we can be sure that 42 lies between 6 and 7
The answer to your question is 724
Answer:
X= 143°
Step-by-step explanation:
You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.
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:
x=30
(Option 2)
Step-by-step explanation:
Well if the <1+<2=180 then you can put the equation as 4x+10+x+20=180. We can simplify that to be 5x+30=180. Minus 30 from both sides: 5x=150; x=30
