Answer:
cos theta = adja/ hypo
adja=8
hypo=17
cos theta= 8/17=0.47
theta= cos^-1 0.47
theta=1.0815
to fine missing side, use Pythagoras
hypo²= oppo² + adja²
17²= oppo² + 8²
289-64=oppo²
oppo²=225
oppo=15
Answer:
Can I see the graph?
Step-by-step explanation:
You need the info of the graph to get the answer.
The bells will ring together again at 10:00am I believe.
Average rate of change = [(g(7) - g(4))/(7 - 4) + (g(8) - g(7))/(8 - 7)] = [(7/2 + 5) - (4/2 + 5)]/(7 - 5) + [(-3(8) + 3) - (-3(7) + 3)]/(8 - 7) = [(8.5 - 7)/2 + (-21 - (-18))/1] = (1.5/2 + (-3)) = 0.73 - 3 = -2.25
The answer to the equation is 5 7/15
