Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33
Square roots that are not perfect squares are irrational.
An example could be √0.5 which equals 0.7071067811...
Answer:
Length of segment
units = 8.94 units
Step-by-step explanation:
Given:
End point of line: (2,1)
Midpoint of line: (-2,-1)
To find length of line segment.
Solution:
Distance from endpoint to midpoint is half the length of segment as the midpoint divides the line into equal halves.
Distance from end point to mid point can be found out using distance formula:

Plugging in points for end point (2,1) and midpoint(-2,-1).





Length of half segment
units
∴ Length of segment =
units
