Question

Find the length of the hypotenuse.

Answer 1

x^2 + y^2 = r^2

r = hypothenuse. This is the Pythagorean theroem

Answer 2

so solve for r?

Answer 3

yes

Answer 4

this is 45 degree right triangle,

so there is a special rule to find the sides..

45 - 45 -90
x - x - xsqrt 2

Answer 5

so then i could set it up like 45^2+3sqroot 2^2=r^2?

Answer 6

oh

Answer 7

the line across from 90 degree angle is the hypothenuse, which is the x sqrt 2 side

Answer 8

no 45 is a angle degree...

Answer 9

okay
