Joel is constructing a line perpendicular to BW←→−. He has already constructed three arcs as shown. He moves his compass point to W to construct a fourth arc.

What must be true about the width of Joel’s compass opening before he draws the arc?

It must be wider than it was when constructing the arc above P.

It must be narrower than it was when constructing the arc above P.

It must be the same as it was when constructing the arc above P.

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

i’m here for points.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
