Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.
Since they do not have all 3 congruent angles, they are not similar.
Step-by-step explanation:
Draw picture of 2 points (-1, 7), (1, 5) at line x and y
and use the formula
slope = (y2 - y1)/(x2 - x1)
If convexity to the right slope +
If convexity to the left slope -
Answer:
Step-by-step explanation:
Simple interest = 
End of first year = 650+19.5 = $669.50
End of second year = 669.50+19.5 = $ 689
End of third year = 689+19.5 = $708.50
End of fourth year = 708.50 +19.5 = $ 728
End of fifth year = 728 +19.5 = $747.50
Answer:
The difference between the area of the two circles is 15.7m
Step-by-step explanation:
I swear these be helping me with the CIEs coming up in May xD
Okay so the formula for a circle is
The diameter is the double of the radius so
Cirlce A has a diameter of 4m so a radius of 2m



Circle B has a diameter of 6m so a radius of 3m



To find the difference subtract 12.57 from 28.27

The difference between the area of the two circles is 15.7m
