Answer 1

I don't have enough information to compute x. Could you either

- upload the diagram, or
- type the full problem text (which sides/angles are given and how they're arranged)?

If this is a right triangle, you'll use the Pythagorean theorem (for legs a and b and hypotenuse c):
c^2 = a^2 + b^2
or
a^2 = c^2 − b^2

If it's a non‑right triangle, use the Law of Cosines (for sides a, b, c and included angle γ opposite side c):
c^2 = a^2 + b^2 − 2ab·cos(γ)

If you post the missing diagram/info I will compute x and give the answer rounded to the nearest tenth.
