Step-by-step explanation:
EF = 6x - 4
and it is also the combination of EG and GF.
so,
6x - 4 = EG + GF = EG + 13
6x = EG + 17
now, we have additional information. EF bisects CD. that means it cuts CD in half.
and that means both banks must be off equal size.
5x - 1 = 7x -13
12 = 2x
x = 6
so, back to the first problem
6×6 = EG + 17
36 = EG + 17
19 = EG
The 2 angles are complemantary or form right angles so

so

. Plugging that into BDC we get 11
Answer:

Step-by-step explanation:
From the question we are told that:
Slant Height of Kite

Since Emma,The Kite and Andrew forms a right angle triangle
Generally the equation for distance between Andrew from Emma is mathematically given by



Skewed left uniform is the answer I think I'm sorry if its wrong.
