Atractor has a rear wheel with a 2-meter diameter and a front wheel with a 1-meter diameter. two points on the outer rims of the tires, a and b, are labeled in the picture. the height above the ground, in meters, of point a is a function of the distance, in meters, x, that the tractor moves forward. the graph of this function is shown. which function represents the height above the ground, in meters, of point b? a b(x)=0.5+cosx b b(x)=0.5+0.5cos(x2) c b(x)=0.5+0.5cosx d b(x)=0.5+0.5cos(2x)

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
