We observe that we have a rectangle triangle. For this case we can use the following trigonometric relationship: sine (45) = (5 * root (2)) / h From here, we clear the value of h: h = (5 * root (2)) / sine (45) Rewriting we have: h = (5 * root (2)) / (root (2) / 2) h = (2 * 5) * (root (2) / root (2)) h = 2 * 5 h = 10 Answer: h = 10 Option F
