Maria has three children. there is two years age difference between each child. the total ages of all three children is 36 years. tina is the youngest child. how old is tina? let t = the age of tina. which formula will calculate tina's age? a) 3t+2=36 b)t+2t+3t=36 c) t+(t+2)+(t+4)=36 d) t+2(t+2)+4(t+4)=36

not sure but I think it is A

Step-by-step explanation:

hope this helps

< 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)
