Answer:
9. 19.4
10. 15.8
11. 16.6
Step-by-step explanation:
The appropriate relations are all given. Fill in the given numbers and solve for the unknown.
9. x^2 +8^2 = 21^2
x^2 = 441 -64 = 377
x = √377
x ≈ 19.4
__
10. sin(33°) = x/29
x = 29·sin(33°)
x ≈ 15.8
__
11. cos(55°) = x/29
x = 29·cos(55°)
x ≈ 16.6
