The temperature of a city was 28⁰C on Tuesday. The temperature rose by 1.5⁰C on everyday upto Friday and fell by 2.5⁰C on Saturday. What was the temperature of the city on Saturday

30 degrees

Step-by-step explanation:

1.5 x 3 (days until friday from tuesday) = 4.5

28 + 4.5 = 32.5

32.5 - 2.5 = 30 degrees

< 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)

sorry but i cant draw that
