HELP!! You walk 130 m E and then turn and walk another 43m [E 28 degree S] what is the total displacement?

Total displacement 155 m

Explanation:

From the question, the formula to apply will be that of cosine rule where:

where

a= 43 m , b=130m and c =? , <C=28° + 90° =118°

Substituting values in the equation as;

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
