Answer:
2) 92.2km
3) B
4) 4.8m
Step-by-step explanation:
Equation: a² + b² = c²
2)
60² + 70² = c²
3600 + 4900 = c²
8500 = c²
√8500 = c
92.2 = c
3)
12² + 4² = c²
144 + 16 = c²
160 = c²
√160 = c
12.6 = c
4)
4.5² + 1.6² = c²
20.25 + 2.56 = c²
22.81 = c²
√22.81 = c
4.8 = c
Common difference = -16-(-20) = 4
nth term = -20+(n-1)4
