A = 45
b = 75
c = 37
d = 137

a-
whenever the angle is shaped like that they are equal i forgot the actual property name though

b-
and the known angles up (so 45 and 60) then subtract 105 from 180 to get 75 which is the answer

c-
add the known angles then subtract from 180 (so add 75 and 68) then u should get 37

d-
add all known angles then subtract from 180 (so add 37 and 100) you should get 43
then ur gonna subtract 43 from 180 to get the answer which is 137

Using properties of the logarithm, you can rearrange the integrand as

\dfrac12\ln(2x^2)=\dfrac{\ln2+\ln x^2}2=\dfrac{\ln2+2\ln x}2=\ln\sqrt2+\ln x

Then recall that the integral of \ln x is

\displaystyle\int\ln x\,\mathrm dx=x(\ln x-1)+C

(or you can find that out by integrating by parts) and so

\displaystyle\int\frac12\ln(2x^2)\,\mathrm dx=(\ln\sqrt2)x+x(\ln x-1)+C
