Answer:
Your answer is 15.2
Step-by-step explanation:
use the formula a² + b² = c²
In this case, you know what a and c are.
a = 13
c = 20
Put those two into the formula.
13² + b² = 20²
13² = 169
20² = 400
169 + b² = 400
Bring 169 over to the other side to get b² by itself. do this by subtracting it from 400.
400 - 169 = 231
b² = 231
Now we need to get rid of the exponent. To do this, get the square root of both sides.
√b² = √231
b = 15.1986841536...
Finally, round your answer to the nearest tenth like the question tells you to.
15.2
Therefore:
b = 15.2
