Answer:

59

29.33

Explanation:

Recall SOH CAH TOA

SOH= Sinα=opposite/hypotonouse

CAH= cosα=adjacent/hypotonouse

TOA= tanα=opposite/adjacent

To find angle C we'll use TOA

which means we take the lenght opposite to d and adjacent to d

which means we have

tand=10/6

d=tan⁻1(10/6)

d=59

to find length z let's use SOH CAH TOA again (for the practice)

This time let's use angle z and SOH

which means we have

sin(64.5)=z/32.5

Solve for z

32.5sin(64.5)=z

z=29.33

*note* if you use a²+b² for number two you get a sligthly different answer. This is because when they rounded when they wrote 64.5**
