Step-by-step explanation:
"soh-cah-toa"
Just an easy way to remember how Sine, Cosine and Tangent work:
Soh...
Sine = Opposite / Hypotenuse
...cah...
Cosine = Adjacent / Hypotenuse
...toa
Tangent = Opposite / Adjacent
28/4=7 Therefore 1/4 of 28 is 7
Answer:
<h2>D</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about</h3>
first note: it will be more easy if we solve the inequality first
so let's solve it together




so what we get
we get that x is greater than 12
<h2>so the answer would be d</h2>
Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building
