5x-6y=10
-5x -5x
-6y=-5x + 10
y-yV1=m(x-xV1)
y+1 = -5 (x+6)
destribute the -5 to the parinthease.
y+1 = -5x - 30
-1 - 1
y= -5x -31

Answer:
Option B. 5.9 m
Step-by-step explanation:
step 1
Find the length of BC
we know that
tan(28°)=BC/AB
BC=(AB)tan(28°)
substitute values
BC=(85)tan(28°)=45.2 m
step 2
Find the length of BD
we know that
tan(31°)=BD/AB
BD=(AB)tan(31°)
substitute values
BD=(85)tan(31°)=51.1 m
step 3
Find the length of CD
we know that
CD=BD-BC
CD=51.1-45.2=5.9 m
