Question

I need help ppl this is due tomorrow thank yooou

Answer 1

Answer:

8.62

Step-by-step explanation:

Use the Pythagorean theorem.

b= $\sqrt{c^{2}-a^{2} }$

b=$\sqrt{10.5^{2}-6^{2} }$

b= $\sqrt{110.25-36$

b=$\sqrt{74.25}$

b= 8.62

Answer 2

To solve you have to use Pythagorean Theorem:
a^2+b^2 = c^2
You’re looking for b so the formula would be:
b^2 = c^2-a^2
10.5^2-6^2
110.25-36
74.25
The square root for 74.25 is 8.61684396...
But it tells you to the nearest tenth so the answer would be 8.6
