Answer:
fgi = 48
fgh = 24
hgi = 24
Step-by-step explanation:
Bisection divides an angle into two equal angles,
So,
4x - 20 = 3x - 9
4x - 3x = - 9 + 20
x = 11
fgi = 3x - 9 + 4x - 20
= 3x + 4x - 20 - 9
= 7x - 29
= 7 ( 11 ) - 29
= 77 - 29
fgi = 48
fgh = 3x - 9
= 3 ( 11 ) - 9
= 33 - 9
fgh = 24
hgi = 4x - 20
= 4 ( 11 ) - 20
= 44 - 20
hgi = 24
Answer: $51.00
Step-by-step explanation:
Since $0.20 is charged per minutes , that is , the amount charged for 300 minutes will be :
300 x 0.20 = $60
Her monthly cell phone plan charges a flat monthly fee of $25.00 , that is the total amount charged will be
$60 + $25
= $85
There is a 40% discount , then we have
40% of $85
= $34
So, the amount of her first cell phone bill = $85 - $34
= $51.00

Answer:
8 feet
Step-by-step explanation:
it actually will be 8 feet
Step-by-step explanation:
> find the angle of center circle:
cos~¹ 5/(5+12) = cos~¹ 5/17 = 72°
so the sector area of the shaded
region =
(360-72)/360 × 3.14 × 5²
= 288/360 × 78.5
= 62.8
> the height of triangle (red Line) =
4×tan 72° = 4× 3.078 = 12.31
the height of pyramid (green
Line) = √12.31²-8.5² =√74.16
= 8.61
so the volume of pyramid =
⅓×(17×8)×8.61 = 390.32
