Easy math question help

Answer 1

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
