By definition of supplementary angles, m∠1 + m∠2 = (a) and m∠2 + m∠3 = (b). Then, m∠1 + m∠2 = m∠2 + m∠3 by the (c). Subtract m∠2 from each side. You get m∠1 = (d), or ∠1 ≅ (e).

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,

ratio is 2 : 9

the answer is three

13.5 : 3

c
