The number 943 is between what two tens

943 is between 94 tens and 95 tens

Step-by-step explanation:

The number 943 is between what two tens

Lets round the number 943 to nearest tens to the left and then to the right.

When we round the number 943 to the nearest tens to the left, it becomes 940. 940 can be written as 94 tens

When we round the number 943 to the nearest tens to the right, it becomes 950. 950 can be written as 95 tens

So 943 is between 94 tens and 95 tens

< 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)
