Question

Solving the missing side. Find the missing side. Round to the nearest tenth. Please show your work. Part 3. #9-10

​

Answer 1

Answer:

9. 16.6 units

10. 18.1 units

Step-by-step explanation:

9. We are given the opposite and adjacent sides of the angle 38 degrees, so we want to use tangent, which is opposite / adjacent:

$tan(38)=13/x$

$x=13/tan(38)$ ≈ 16.6 units

10. We are given the adjacent and hypotenuse sides of the angle 25 degrees, so we want to use cosine, which is adjacent / hypotenuse:

$cos(25)=x/20$

$x=20*cos(25)$ ≈ 18.1 units

Hope this helps!
