What is the missing step in this proof? OA.
Statement: 24 25, and 21 23.
Reason: Alternate Interior Angles Theorem
ОВ.
Statement: De is parallel to AC
Reason: AB is a transversal cutting De and AC
Ос.
Statement: 212 24, and 23 - 25.
Reason: Alternate Interior Angles Theorem
OD.
Statement: 2124, and 23-25.
Reason: 21 and 24, and 23 and 25 are pairs of supplementary angles.

We are given

a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius

so, thermal conductivity is

while we want the batting thermal conductivity in  w/cm•c

The only difference is that metre and cm

so, we need to change metre into centimeter

we know

1m =100cm

so, we can write thermal conductivity as

we can replace 1m as 100cm

now, we can simplify it

so, thermal conductivity is
