Answer:
15. y<1 16. y>or=-2 17. y>0 18. y<or=3 19. y<or=1200
Step-by-step explanation:
X-7>10
add 7 to both sides
x=17
Using the tangent ratio, the height of the lighthouse from the top of the cliff ≈ 161.2 meters.
<h3>What is the Tangent Ratio?</h3>
For solving a right triangle, the tangent ratio that can be applied is: tan ∅ = opposite length / adjacent length.
Find the height of the light house and the cliff using the tangent ratio:
tan 51.3 = height/980
Height of lighthouse + cliff = (tan 51.3)(980)
Find the height of the cliff only using the tangent ratio:
tan 47.3 = height/980
Height of cliff = (tan 47.3)(980)
Height of the lighthouse from the top of the cliff = (tan 51.3)(980) - (tan 47.3)(980)
Height of the lighthouse from the top of the cliff ≈ 161.2 meters.
