The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
2(5k+1)
2x5x2+1 =21
K=2 | 21
2x5x3+1 =31
K=3 | 31

Answer:
Step-by-step explanation:
arc BE is the same as the interior angle, or 76°
BE = 76 °
we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°
Now we know all the arcs but arc CD
so use the idea that all the way around the circle is 360°
360 = 76 + 104 + 140 + CD
360 - 76 - 104 - 140 = CD
40 = CD
CD = 40 °
Answer:
x = 5, -3
Step-by-step explanation:
x² - 15 = 2x
x² - 2x - 15 = 0
(x - 5)(x + 3) = 0
