Answer:
∠Z ≈ 12°
Step-by-step explanation:
Using the Sine Rule in ΔXYZ
=
, that is
=
( cross- multiply )
48 × sinZ = 10 × sin96° ( divide both sides by 48 )
sinZ = 
Z =
(
) ≈ 12°

Answer:

Step-by-step explanation:
The average rate of change between two points on a graph is ...
average rate of change = slope = rise/run
The rise over the given interval is the function value at x=8 less the function value at x=5. That is, ...
rise = 1 - 10
The run is the difference in the x-values:
run = 8 - 5
Then the average rate of change is ...
average rate of change = rise/run = (1 -10)/(8 -5)
_____
Here, the points are written as (x, y), so the only pair we're interested in is ...
(5, 10) and (8, 1)
