We find the length of the arc followed by the needle. For this, we first need to convert the subtended angle to radians:
96/∅ = 180/π
∅ = 1.68 rad
S = r∅
S = 24 x 1.68
Distance covered by needle = 40.32 cm
Answer:
115 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so if x is the angle you're trying to have you get:

Answer:
Between 30 and 31
Step-by-step explanation:
A = L * W
A = 99
L = W + 2
99 = W(W + 2)
99 = W^2 + 2W
W^2 + 2W - 99 = 0
(W - 9)(W + 11) = 0
W - 9 = 0
W = 9
W + 11 = 0
W = -11 (extraneous solution....this one does not work)
L = W + 2
L = 9 + 2
L = 11
check..
A = L * W
99 = 11 * 9
99 = 99 (correct)
so the length (L) = 11 and the width (W) = 9
