A(7, -2) B(-4, 9) C(-3,-1)
AB² = (7 - -4)² + (9 - -2)² = 121 + 121 = 242
AC² = (7 - -3)² + (-2 - -1)² = 100 + 1 = 101
BC² = (-3 - -4)² + (9 - -1)² = 1 + 100 = 101
Since AC² + BC² ≠ AB² this isn't a right triangle
It is clearly an isosceles triangle because AC² = BC²
Answer: Isosceles
Answer:
r= 2 √(15/π)
Step-by-step explanation:
Given that :
Area of circle =60sq cm
radius=√60/π

Hence the radius can be written as 2 √(15/π)

Dimes
Calculating total coins
P(for a dime) 
Calculating remaining coins
Nickels 
P(for nickel draw in second)
P(for a dime after that a nickel, without replacement)
A=bh/2=(19 x 11)/2=(209)/2=104.5 inches
