step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

just get this app called photo math it should be able to do those
