Step-by-step explanation:
Answer:
We form rectangular triangle. Ninghty degrees angle.
Step-by-step explanation:
1) the top of the billboard is
7+12=19 feet above the ground
2) the eye of the cow is
4 feet high
3) the opposite side of the triangle is
19-4=15 feet
4) the distance between cow eye and billboard is
"x"
5) tg (θ)=15/x
6) x=15/tg(Θ)
First, you must combine all like terms.
'5y' and a '-y' account to a positive '4y'.
7=4y-13
add 13 to both sides to cancel out the -13 on the right side of the equation. we're left with:
20=4y
you must divide by 4 on both sides to get 1y by itself, to know its value. we do so and we get,
y= 5
hope that helped. (:
