Step-by-step explanation:
Sum of interior angles in a polygon = 180°(n - 2).
Size of interior angle in a regular polygon
= 180° - 360°/n
= 180° - 360°/12
= 180° - 30°
= 150°.
Х - has Danny
2 - has Carly
--------------------------
9 - have together
x + 2 = 9
x = 9 - 2
x = 7 - has Carly.
Answer:
Step-by-step explanation:
d = c-b / a-n
Make b the subject
d (a - n) = c - b
-b = d (a - n) / c
Divide both sides by - 1
-b / -1 = d (a - n) / c ÷ -1
b = d (a - n) / c × 1/-1
= d(a - n) / - c
= ad - an / - c
