haha could you please continue? i am so lost...thank you for all your help. i apperciate it!
Where are you "so lost?" Soroban has given you the plan to solve this problem. I'll go just a bit further into the plan:
In right triangle BAC, with right angle at A, the two legs are BA and CA, and
tan C = AB/AC
You know that angle C has a measure of 49.3 degrees, and that AC = 673:
tan 49.3 = AB/673
Multiply both sides by 673:
673* tan 49.3 = AB
That will give you the length of leg AB, which is also a leg of right triangle ABD. The length of the other leg DB of this triangle is the height h you are looking for. In this triangle,
tan (angle DAB) = DB/AB
And you are given that the measure of angle DAB is 61.6 degrees, so
tan 61.6 = h/AB
But you will have found AB already, right? So, substitute the length you got for AB, and solve for h......
