2450 is the correct answer because if you multiply 3500 x .70 then you get 2450. Hope this helped
C. 30°,60°,90° due to the fact that it's a right triangle
Remark
You are dealing with a right angle triangle. You can use one of Sin(x) Cos(x) or Tan(x). Since the Hypotenuse is involved and since you are given the adjacent side, Cos(71) is what you will need.
Solution
H = BC
Cos(x) = adjactent / hypotenuse
Cos(71) = 6.3 / H Multiply both sides by H
H * Cos(71) = 6.3 Divide by Cos(71)
H = 6.3 / cos(71) Cos(71) = 0.32557
H = 6.3 / 0.32557 Divide
H = BC = 19.351 Answer
The second one. There is a side, an angle, and another side.
I’m pretty sure it’s the second one if not I’m so sorry
