Nope. Perimeter = sum of all sides
P = 20 + 11 + 20 + 11 = 62 and not 64
So, it is not possible.
Answer:
3240°
Step-by-step explanation:
For a regular icosagon,
sum of interior angles measure=180(n-2)°
180(20-2)
180(18)=3240°
Answer:
22 feet
Step-by-step explanation:
Change 15 feet into inches using the conversion
1 foot = 12 inches, thus
15 ft = 15 × 12 = 180 inches
scale factor = 180 ÷ 3.75 = 48
Thus the actual dimensions of the boat are 48 times the model.
actual length = 48 × 5.5 = 264 inches = 264 ÷ 12 = 22 feet
Answer:
11° and 79°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then the other angle = x + 68 , hence
x + x + 68 = 90
2x + 68 = 90 ( subtract 68 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°
As a check : 11 + 79 = 90
Answer:
7.5* 10^8
Step-by-step explanation:
(1.5 x 10^5)(5 x 10^3)
Multiply the numbers
1.5*5=7.5
Add the exponents
10 ^(5+3) = 10^8
Put back together
7.5* 10^8
This is in scientific notation
