Explanation:

Step1: Identify Heights

Washington Monument height: $169.294$ m. Gateway Arch height (from options, likely $192$ m? Wait, no, Gateway Arch is 192 m? Wait, no, the options: Wait, the problem's Gateway Arch height—wait, the user's image: let's recheck. Wait, the Washington Monument is 169.294 m. The Gateway Arch in St. Louis is 192 m? Wait, no, the options: A.22.730, B.37.270, C.251.218? Wait, no, maybe I misread. Wait, the Washington Monument is 169.294 m. Let's check the Gateway Arch height. Wait, maybe the Gateway Arch height is 192 m? No, wait, the options: Let's see the calculation. Wait, maybe the Gateway Arch height is 192 m? Wait, no, the options: Let's do subtraction. Wait, the correct Gateway Arch height is 192 m? Wait, no, 169.294 + 22.730 = 192.024, which is close to 192 m. Wait, so 192 - 169.294 = 22.706, which is ~22.730. So Step1: Get Washington Monument height: $169.294$ m. Gateway Arch height: let's assume from the options, the difference is 22.730, so Gateway Arch height is $169.294 + 22.730 = 192.024$ m, which matches the actual Gateway Arch height (192 m). So Step2: Subtract Washington Monument height from Gateway Arch height. Let's calculate $192.024 - 169.294 = 22.730$ m.

Step2: Perform Subtraction

Height difference = Gateway Arch height - Washington Monument height. Let's use the numbers: If Gateway Arch height is $192.024$ m (approx $192.024$) and Washington Monument is $169.294$ m, then $192.024 - 169.294 = 22.730$ m.
