Answer:
A+C.................................................
We can find this out by using the parameter equation for a circle
r = radius = 11
p = 69.115
If we round
p = 69.12
You can't tell the dimensions from the area. There are an infinite number of correct answers. The length of the fence is 2 times (length of the pond + width) and the length and width can be anything, just as long as their product is 2956.5 .
Answer:
0.51
Step-by-step explanation:
Use knowledge of trigonometric ratios to find cos(F).
Remember:
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
In this case, we're dealing with cosine, so let's use the cosine formula.
cos(F) = adjacent/hypotenuse
When you look at the diagram, you can see that the you are only given opposite and hypotenuse, so we still need the length of the adjacent side.
Since this is a right triangle, we can use the Pythagorean Theorem, , to find the length of the adjacent side.
So + 56² = 65².
Solve for a.
+ 3136 = 4225
= 4225 - 3136 = 1089
a = √1089 = 33
Now that we know the length of the adjacent side, we can go back and use the cosine formula.
cos(F) = adjacent/hypotenuse
cos(F) = 33/65 ≈ 0.51

Answer:
Step by step explanation:
Here two triangles are given to us . The two triangles are ∆MNP and ∆RST. They are similar to each other . That is ,
Now we know that the corresponding sides of the similar triangles are proportional . Hence here ,
Here we are given the value of side NP as 7 and ST as 2 . So here we can find out the scale factor by dividing these two .
