Answer: (x,y) = (1,6)
Step-by-step explanation:
Explanation:
x + 3y = 2
<u>Converting it to slope intercept form</u>:
y = mx + b [where m is slope, b is y-intercept]
<u>Make y the subject</u>:




<u>which reveals slope</u>:

I'm going to assume that you're asking for the<em> equation</em> of that circle.
It's
<u>(x + 4)² + (y - 3)² = 16</u>
Answer:
12.68°
Step-by-step explanation:
We know all three sides (18, 80, 82), but we only need two: 18, and 82. Why? What we do here is find the arcsin of the first leg divided by the hypotenuse.
arcsin(18/82)
<em>18/82 is the same as 9/41, which equals 0.21951 repeating (all 5 digits after the decimal are repeating, by the way).</em>
arcsin(0.21951)
<em>What you see above this statement equals 0.22131 radians.</em>
0.22131 rad
<em>To convert this to degrees, multiply by 57.2957795.</em>
0.22131 * 57.2957795
<em>0.22131 times 57.2957795 is 12.680128961145.</em>
12.680128961145°
<em>The directions say the final answer has to be two decimal places. So this becomes 12.68 (0 is less than 5, so round down).</em>
12.68°
Angle A is 12.68°.
