Answer:
h = 2A/b
Step-by-step explanation:
multiply both sides by 2
2A = bh
divide both sides by b
2A/b = h
The central angle corresponding to AOB is half of the 8pi/9 radians mentioned, meaning that the central angle of AOB is 4pi/9.
Converting that to degrees:
4pi/9 180 degrees
-------- * -------------------- = 80 degrees.

Answer:
<h2> 18.3</h2>
Step-by-step explanation:
from cosines theorem:
t² = 11² + 14² - 2•11•14•cos87°
t² = 121 + 196 + 308•0.05236
t² = 333.12688
t = √333.12688
t = 18.2517... ≈ 18.3
