Angle C would be 55 degrees. A straight line is 180 degrees so you would do 180-125 which equals 55. Hope this helps!
Answer:
Step-by-step explanation:
11 degrees to radians: 1 degree =57.296 radians
L = (11 degrees)/(57.296) x (11 in) = 2.111848 in
C=2x Pi x R so 2x3.14x17.5 = 109.9
Step-by-step explanation:
a)
total no. of pupils is not more than 24
therefore first equation is
(x+y) ≤ 24. ....(1)
No. of girls exceeding the no. of boys by atleast 4
(y-x) ≥ 4. .....(2)
b) Now Liza chooses 8 boys
Maximum no. of girls = ?
Using first inequality
y+8= 24 ( maximum value of less than or equal to function is equal to itself)
Therefore,
y= 24-8
=16
Minimum no. of girls = ?
Using second inequality
y-8 =4 (minimum value of greater than or equal to function is equal to itself)
Therefore,
y= 4+8
y=12
Answer:
a) 2linear inequalities
(x+y) ≤ 24
(y-x) ≥ 4
b) Max no. of girls = 16
Min no. of girls = 12
Hope it helps...
