Question

Pls help for math i need help

Answer 1

Answer:

6.1 inches

Step-by-step explanation:

you are using the pythagorean theorem.

$6.2^{2} + b^{2} = 8.7^{2}$ so 6.2 and 8.7

$38.44 + b^{2} = 75.69$ so 38.44 and 75.69

$b^{2} = 37.25$     you subtract 38.44 from both sides

$\sqrt{b^{2} } = \sqrt{37.25}$ so $b^{2}$ and 37.25

b = 6.103277808

so the length b is about 6.1 inches
