Answer:
Step-by-step explanation:
The formula for arc length is
where theta is the measure of the central angle and r is the radius. We have both of those pieces of info; filling in:
and simplifying a bit:
and a bit more:
and finally, to
AL = 2.09 m
Add the (a,b) and then add (a,c). Find out the number between these two after being added
Answer:
The height of the tree is 30 feet
Step-by-step explanation:
Let
h ----> the height of the tree
we know that
The tree casts a shadow that is 27 feet long
Your friend is 5 feet tall and casts a shadow that is 4.5 feet long
so
using proportion
Find out the height of the tree
Answer:
4 sqrt(2) =c
Step-by-step explanation:
The base is the triangle
We can use the Pythagorean theorem to solve
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
4^2 + 4^2 = c^2
2 * 4^2 = c^2
Take the square root of each side
sqrt(2 * 4^2) = sqrt(c^2)
sqrt(2) *sqrt( 4^2) = c
4 sqrt(2) =c
