Question

What is the length of side x in the triangle below?
(picture below)

Answer 1

The last angle will be 45 degrees also so you have an isosceles right triangle. So,

15^2 + 15^2 = x^2

It's just the Pythagorean theorem. You can use it. It's just that you needed to know that the other side was also 15.

Answer 2

x^2 = 2(15^2) x = 21.21 or (15)(sqrt(2))

Answer 3

damn i thought it was 10. i divided 450 and 45

Answer 4

Well, that 45 is for the angle. So the real key to this is realizing that the other leg is also 15. From there it's just the Pythagorean theorem. Don't worry if you didn't get it before, because you have it nailed now.

Answer 5

ohhh ok

Answer 6

The thing is that you understand it now and I think you do now.

Answer 7
