Answer:
40.8 yd
Step-by-step explanation:
From SOH CAH TOA, you know that the relationship between the adjacent side (distance to tower) and opposite side (height of tower) of the relevant triangle is given by ...
... tan(11°) = (height of tower)/(distance to tower)
Multiplying by the denominator, we have ...
... height of tower = (distance to tower) × tan(11°)
... = (210 yd) × 0.19438 ≈ 40.82 yd
Rounded to the nearest 0.1 yd, the height is 40.8 yd.
