Answer:
x = 3.888
Explanation:
You know what the givens are.
- You have 11 degrees for the angle
- The triangle is a right triangle
- You know that the adjacent side is 20 units.
- You know you need to solve for x.
Everything is there.
Equation
Tan(11) = x / 20
Solve
Tan(11) = 0.1944
0.1944 = x / 20 Multiply both sides by 20
20*0.1944 = x Switch sides
x = 20 * 0.1944
x = 3.888
