Hello: If the content hasn't changed, the answer is as follows: 10. Measure the distance from the starting line to the heel of the following footprint, and then convert it according to the scale to get Xiaoming's long jump score. I measured 2.3cm in the book, which means the actual distance on the map is 2.3 ÷ (1150) = 3.45 m.11,(1) ∠/kloc-. ∠ 1 and ∠2, ∠3 and ∠4 are internal angles (2)∠ 1 and ∠2 are AB and DC cut by BC, ∠3 and ∠4 are AD and BC cut by BE. ∠ 1 and∠ 2 are ipsilateral internal angles, and∠ 3 and∠ 4 are isosceles angles.
