The answer is 5 in a close dot going --->
Which is D.)
The picture is to show how it looks in Plato.
Answer:
16.2 units
Step-by-step explanation:
Greater angle: 180 - 72 = 108
D² = 10² + 10² - 2(10)(10)cos(108)
D² = 261.8033989
D = 16.18033989
Answer:
The actual distance between them is 92.5 km
Step-by-step explanation:
Rewrite Equations
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30
y=−20
(Simplify both sides of the equation)
Answer: x=10 y=-20 (10,-20)
