we know that s = 3, so plug it in.
P = 6(3)
P = 18
perimeter = 18 km
1/√2
Step-by-step explanation:
Imagine a right-angled triangle, for e.g. Triangle ABC,
Where
B = 90°
Remember your Toa Cah Soh.
sin 45° = opposite / hypotenuse
If theta = 45°
Angles A and C = 45° (Sum of angles in a triangle equal = 180°)
Since theta are the same, we can also deduce that the length AB and BC are the same.
Take for example AB = BC = 1 = opposite
By the Pythagorean theorem,
AB² + BC² = AC²
1² + 1² = AC²
2 = AC²
AC = √2 = hypotenuse
Therefore:
sin 45° = opposite / hypotenuse
sin 45° = 1/√2
Answer:
The length of each side of the square park is 2,400 ft
Step-by-step explanation:
we know that
The scale is 
step 1
Remember that
1 ft=12 in
The length of each side on the map is 1 ft
Convert ft to in
1 ft=1(12)=12 in
step 2
Find the length of each side of the square park
using proportion
Let
x ----> the actual length of each side of the square park
Answer:
44.5
Step-by-step explanation:
If the last digit is 5 or above you have to round up but since 4 is below 5 you have to round down. This means you will round 44.54 to 44.5
