Answer:

1. 23

2. 5.83 (5.8 rounded)

3. 1.18 (or 1.2 rounded)

4. unsure how to solve, sorry

Explanation:

your formula: a^2+b^2=c^2

1. 20^2+13^2=c^2

400+169=569

(take the square root of 569)

c=23

2. 15^2+b^2=17^2

225+b^2=289

(subtract 225 from both sides)

b^2= 34

(take the square root of 34)

b=5.83 (or 5.8 rounded)

3. 0.2^2+b^2=1.2^2

0.04+b^2=1.44

(subtract 0.04 from bot sides)

b^2=1.4

(take the square root of 1.4)

b=1.18 (or 1.2 rounded)

4. unsure how to solve, sorry
