Answer:
Below.
Step-by-step explanation:
7cm
(r) = 3.5cm
l = 5.5cm
Arc length = (Ѳ/360)2∏r
5.5 = (Ѳ/360)2*3.14*3.5
5.5 = (Ѳ/360)21.98
Divide 21.98.
5.5/21.98 = Ѳ/360
Ѳ/360 = 0.25
x 360.
Ѳ = 90
Arc angle is 90 degrees.
Answer:6 1/3 or 19/3
Step-by-step explanation:
Answer:
The Length of AC is 17 units.
Step-by-step explanation:
Given:
BL = LC
AD = 24
AL = LD
AL = LD = half of AD = half of 24 = 12. { FJ bisect AD }
Also,
CD = 2 + LC
To Find:
AC = ?
Solution:
By Addition Property we have
LC + CD = LD ............{ L - C - D }
LC + ( 2 + LC ) = 12 ..........{substituting the given values}
∴ 2(LC) = 12 -2
∴ 2 (LC) = 10
∴ 
Again, By Addition Property we have
AC = AL + LC ................{ A - L - C }
AC =12 + 5
∴ AC = 17 units
∴ The Length of AC is 17 units.
Answer:
54 years
Step-by-step explanation:
Joyce age = x
Alex age = y
3x = 2y - - - (1)
y - 9 = 2(x - 9)
y - 9 = 2x - 18
-9 + 18 = 2x - y
9 = 2x - y
y = 2x - 9 - - (2)
3x = 2y
3x = 2(2x - 9)
3x = 4x - 18
18 = 4x - 3x
18 = x
Hence,
Mrs stone is 3 * 18 = 54 years
The answer is it’s 5 pie over 4
