Question

Does someone mind helping me with this question? Thank you!

Answer 1

Answer:

I dont mind :D These were my favorite! They are actually really simple. Dont overthink it. It even gave you a hint!

It says a^2 + b^2 = c^2

We can substitute what we do have which is a = 10 and c = 15

10^2 + b^2 = 15^2

Now we square it

100 + b^2 = 225

Next, all we have to do is subtract the 100 from our answer so 225-100 which is 125, so b has to be 125!!! Because 125 + 100 is 225 :D

Step-by-step explanation:

Answer 2

Given:

• Hypotenuse ( c )= 15
• Side 1 ( a )= 10

To find:

The length of "b" using Pythagoras Theorem.

Solution:

${a}^{2} + {b}^{2} = {c}^{2}$

${10}^{2} + {b}^{2} = {15}^{2}$

$b = {15}^{2} - {10}^{2}$

${b}^{2} = 125$

$b = \sqrt{125}$

$b = 11.18033989$

$b = 11.2 \: (nearest \: tenth)$

Therefore, the length of "b" is 11.2
