Answer:
Question 5:
a) 65 degrees
b) 11
Question 6:
a) 15.6
b) 6.4
Question 7:
a) 10
b) 20
Question 8:
a) EF = 14.4
Question 9:
a) x = 6
b) y = 22.5
Step-by-step explanation:
Answer : = 55/9
step by step explanation : Divide both sides of the equation by the same term
55=9x
55/9= 9x/9
The geometry of the problem does not seem well-described here. Assuming the spotlight beam and the observation are in the same vertical plane, there are two possibilities for the height:
.. 446 m . . . . . spotlight is aimed toward observer
.. 772 m . . . . . spotlight is aimed away from observer
See the attachment for the geometry. Choose the answer corresponding to the geometry of the problem.
