Answer:
In the picture
Step-by-step explanation:
I hope that it's a clear explanation.
Y=2x+0. The two would be next to the x, because that represents the slope. And it would plus zero, because zero is the initial value, since it's passing through the origin.
The law of cosines is used for this purpose. It tells you
c² = a² + b² - 2ab×cos(C)
Solving for the angle C gives
C = arccos((a² + b² - c²)/(2ab))
C = arccos(( 17² + 15² - 19²)/(2×17×15))
C = arccos(153/510)
C ≈ 72.5424°
The measure of the angle opposite the longest side is about 73°.
Answer:
n = (177-45)/2
