Answer:

In alphabetic order:

x can be found with pythagorean theorem, since triangle ADC is right in D.

x= \sqrt {7^2-2.2^2} \approx 6.6

y and z are 7 times respectively the sine and cosine of angle ACB.

y= 7sin\ 52\° \approx 5.5\\z=7 cos\ 52\° \approx 4.3

Finally, \theta  can be calculated by determining the arc sine (or inverse sine) of the ratio CD over AC

\theta = sin^{-1} (\frac{2.2}7) \approx 18.3\°
