For all of the triangles you have to use Sin, Cosin, or Tangent. Sin= opposite/hypotenuse, Cosin=adjacent/hypotenuse, and Tangent= opposite/adjacent.
Question 2-
You have the hypotenuse and you are trying to find the adjacent. Cos(35)=x/51
Multiply the 51 over and now you have 51Cos(35)=x. x=41.77m
Question 3-
Tan(30)= x/24. 24Tan(30)=x. x= 13.856m
Question 4-
Sin(70)=x/18. 18Sin(70)=x. x=16.9 m
Question 5-
Cos(60)= x/30. 30Cos(60)=x. x=15m
Question 6-
Tan(55)=x/6. 6Tan(55)=x. x= 8.568m
