To solve this problem you must apply the proccedure shown below:
1- The ladder forms an isosceles triangle, because it has two equal sides.
2- Let's call the angle
. To calculate it , you can divide the triangle into two equal right triangles and the angle
will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:



The answer is: 
50° <span>is the measure of angle AFB</span>
because 1+1+1+1=4 and thats 4 1's 1+1=2 2+2=4
Answer:
A coordinate grid that shows a point located halfway between 3 and 4 units to the right and 1 unit down from the origin
Step-by-step explanation:
In a coordinate grid, the y axis is plotted on the vertical axis and the x axis is plotted on the horizontal axis. A is plotted on a coordinate grid at (
) i.e (
). Above the origin is the positive y axis, below the origin is the negative y axis, right of the origin is the positive x axis and left of the origin is the negative x axis.
To plot A on the coordinate axis we need to locate
on the x axis and -1 on the y axis.
is halfway between 3 and 4, since the x coordinate is positive it is located to the right between 3 and 4 and since the y coordinate is negative it is located 1 unit down from the origin.
