The mean room temperature from Monday to Saturday is 25oC and the mean room temperature of Saturday and Sunday is 28oC. if the mean room temperature from Monday to Sunday is 26oC, find the room temperature on Saturday

24 °C

Step-by-step explanation:

Mean =

Given:  Mean room temperature from Monday to Saturday = 25°C

Sum of temperature from Monday to Saturday = 6 x  25°C   [Total 6 days from Monday to Saturday]

=  150°C

Mean room temperature of Saturday and Sunday = 28°C

Sum of temperature of Saturday and Sunday = 2 x28°C

=56 °C

Sum of temperature from Monday to Sunday = 7 x 26°C

= 182 °C

Room temperature on Saturday =  150°C  + 56 °C  - 182 °C

= 24 °C

Hence, the room temperature on Saturday = 24 °C

its c or d   take a lucky guess my dude

< 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)
