Question

Find the unknown length in the right triangle. Simplify the answer if necessary. <3

Answer 1

\[a) \sqrt{10}\]

Answer 2

\[b) 2\sqrt{10}\]

Answer 3

c) 2

Answer 4

d) 58

Answer 5

well using pythagoras' theorem you have

\[b^2 = 7^2 - 3^2\]

so that's the start, the answer is a raducal, so you will need to simplify it

Answer 6

is it b or 6?

Answer 7

It's b. Thanks, but I don't get if it will be B^2 =4^2?

Answer 8

like how does it even turn into a radical lol

Answer 9

\[b2=7^2-3^2=49-9=40=4\times10,b=?\]
