Answer:
11 Minutes
Step-by-step explanation:
$30 - $28.24 = $1.76
$1.76/ 0.16 Cents /minute = 11 Minutes
A₆ =12
a₇ = ?? = x
a₈ 27
In this case x is the geometric mean & as per the formula
geometric mean of 2 numbers =√(a₆ * a₈) = √(12*27)
& x=18.
Proof:
Find the common ratio between a₇ & a₆ ==> = ( x) / 12
now find the common ration between a₈ & a₇ ===> =27 / (x)
x/12 = 27/x ===> x² = 12*27 ==> x² = 324 & x =√324 = 18
Answer:
L = 52°
J = 45°
K = 83°
Step-by-step explanation:
J = L - 7
K = 2L - 21
J + K + L = 180°
∴ (L - 7) + (2L - 21) + L = 180
4L - 28 = 180
4L = 208
L = 52°
J = 52 - 7 = 45°
K = 2 x 52 - 21 = 83°
