Step-by-step explanation:
2 × (First Angle + Second Angle) = 360°
5x + 9x + 26 = 360°/2
14x + 26 = 180°
14x = 180 - 26
14x = 154
x = 154/14
x = 11°
The answer is B.
X = Leonard, y = Liam
x = y + 7
3x + 2y = 96
now we sub
3(y + 7) + 2y = 96
3y + 21 + 2y = 96
5y = 96 - 21
5y = 75
y = 15
x = y + 7
x = 15 + 7
x = 22
<span>Liam has 15 and Leonard has 22. </span>
The radius of the circle is 1km
Let us write down the equation clearly and in a proper manner. This will help in solving the equation very easily.
8^(x + 3) = 16^(x - 1)
(2^3)^(x + 3) = (2^4)^(x - 1)
(2)^3(x + 3) = (2)^4(x - 1)
Then
3(x + 3) = 4(x - 1)
3x + 9 = 4x - 4
4x - 3x = 9 + 4
x = 13
I hope the procedure is clear enough for you to understand. I also hope that this is the answer that has actually come to your desired help.
