C²=a²+b²-2·a·b·cos(C)
c²=(1.5)² + (0.5) -2 ·(l·5) ·(0.5) ·cos(120°)
c²= 3.25
c= √3.25
c=1.802775638
To nearest tenth, c=1.8
3000 + 500 + 60 = 3560

Your calculator can help you out here if you really have no idea that the exponent of 10 tells you the number of zeros: 10^3 = 1000.
Answer:
explanation that will help u get ur answer
Step-by-step explanation:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
