<h2>74</h2>
Step-by-step explanation:
= ( 12 - 3)² - (14/2)
= 9² - 7
= 9×9 - 7
= 81 - 7
= 74

The area of the sector 2π/3 radians with diameter 10 feet 75π feet²
The arc period of a circle can be calculated with the radius and relevant perspective using the arc period method.
Diameter = 10 feet
radius = 5 feet
angle = 2π/3 radians
⇒angle= arc/radius
⇒ 2π/3 radians° =arc/10
⇒ arc =2π/3 radians *10
⇒arc=2π/3 radians*10
⇒arc = 20/π43 feet
Area of a circle = π*r²
= π*5² = π25
∵ area of complete circle is π25
∴ area of 2π/3 radians = π25/2π *2π/3 radians
= 75π answer

so amnt of money is x
x - 5 is Mark's remaining amnt
x - 20 is Susan's remaining amount
x - 5 = 2( x - 20) as he has twice the amnt of Susan
x - 5 = 2x - 40
40 - 5 = 2x - x
35 = x
the original amnt is $35
Answer:
540°
Step-by-step explanation:
If a triangle (3 sides) has 180 degrees then we can figure out the degrees in a pentagon.
180° + 360° = 540°
How? The "top" part could be seen as a triangle (180 degrees), and we know that a quadrilateral's angles add up to 360 degrees, so when we add them together we get out answer!
