Question

Help pls I'm confused

Answer 1

Sorry this took so long, hope this helps

also the "a^2" is meant to mean this "
`a^(2)` "

Explanation:

1) a^2+b^2=c^2

4^2+3^2=c^2

16+9=c^2

25=c^2

`√(25)`=c

5=c

2) a^2+b^2=c^2

15^2+8^2=c^2

225+64=c^2

289=c^2

`\sqrt{225`=c

15=c

3)a^2+b^2=c^2

10^2+50^2=c^2

100+2500=c^2

2600=c^2

`√(2600)`=c

50.99≈c

4) a=
`√(c^2-b^2)`

a=
`\sqrt{15^2-12^2`

a=
`√(225-144)`

a=
`√(81)`

a=9

Answer 2

Explanation:

Pythagorean theorem

Is a^2 + b^2 = C^2

A can be the base

B can be the height

C is the hypotenuse which is the side opposite the right angle

Is that what you don’t understand or?
