The process is as follows:

Method one,

"Slope ratio" is a slope? For "vertical height h"? The ratio of "horizontal width l", as shown below:

From the original question, what is Bobby? 1:√3

Namely H:L? =? 1:√3? ①

Know H 2 again +? L^2？ =? S^2？ ②(? H 2, which is the square of H? )

Simultaneous ① ② type, it is concluded that:

H:S？ =? 1:2? (i.e. vertical side: hypotenuse = 1:2? )

According to the original title, it is150m downhill, that is? S= 150？ rice

So what? h？ =? S×( 1:2)=？ 150×( 1:2)=? 150× 1÷2=? 75? rice

So, Xiaoming 75? rice. ?

Method two,

Because? H:L？ =? 1:√3

Starting from the nature of right triangle, let the angle of the base angle be degrees, we can get

Tan? Answer? =? H÷ L？ =? 1:√3

So what? a=30？ degree

So there is? Vertical edge: hypotenuse? =? 1:2? (sin? 30? =? 1:2? )

Therefore, the rising height is:

h？ =? 150÷2=? 75? rice
