Answer:
4 hours and 7 hours
Step-by-step explanation:
Marcus = x hours
Donnell = x + 3 hours
Total = 11 hours
- x + x + 3 = 11
- 2x + 3 = 11
- 2x = 8
- x = 4
So Marcus practiced 4 hours and Donnell practiced 7 hours
The height of the tower is 42.54 m.
Solution:
The reference image of the answer is attached below.
Given data:
BC = 80 m, ∠C = 28°




Multiply by 80 on both sides, we get
42.536 = h
Switch the sides.
h = 42.536
h = 42.54 m
The height of the tower is 42.54 m.
