Answer 1

@mathmate here it is, sorry to keep you waiting.

Answer 2

Have you done Pythagoras yet?

Answer 3

not really

Answer 4

im sorry, its just my teacher thinks we do

Answer 5

may you still help?

Answer 6

Doesn't really matter. Here it is:
When you have a right-angled triangle (indicated by the little square at angle C), then the square of the length of hypotenuse equals the sum of the squares of the other two sides.
The length of sides of a triangle, in general, are named in lower-case letters of the angle opposite the side, as shown in the above drawing.
Here, we apply Pythagoras Theorem:
\(a^2+b^2=c^2\)
where c is the hypotenuse, the side opposite the 90 degrees angle, C.

Substituting values, a=1, b=2, c=x, we have
\(1^2+x^2=2^2\)
All you need to do now is to solve for x, perhaps using a calculator.

Answer 7

wouldnt it equal the square root of 3?
