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
