Sorry for small handwriting ​

Step-by-step explanation:

4 is added to each number

A/q ,

5x+4/6x+4 = 7/8

Now , cross multiply

7/6x + 4) = 8 (5x + 4 )

42x + 28 = 40x + 32

42x - 40x = 32 - 28

2x = 4

x= 4/2

x= 2

answer :

5x = 10

6x = 12

< 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)
