It’s 9.9 because 3 times 3.3 is 9.9
MAB = 360 - 255 = 105
<ADB = 1/2(mAB) = 1/2(105) = 52.5
Answer
52.5°
Here, x - 2y = 14
x = 14 + 2y
Now, substitute this value into first equation,
4x + 6y = 0
4(14 + 2y) + 6y = 0
56 + 8y + 6y = 0
14y = -56
y = -56/14
y = -4
Substitute it into second equation,
x = 14 + 2(-4)
x = 14 - 8
x = 6
In short, Your Answer would be: (6, -4)
