Look at the diagram of the scenario below. A steep downhill ski slope is
intersected at an angle by a less steep ski slope. Safety fences need to be set up
in the locations shown. The angles of the fences, angles 1 and 2, can be
determined by finding the relationship between the angles a and b.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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)

answer: i think you should do the math and pay attention in class : )
