<h3>Answer: D) Two</h3>

You need the starting point, and another point that helps direct where the ray is aimed. Call these two points A and B.

Saying "Ray AB" means we extend a line through AB such that the line goes forever through B and beyond B, but we do not do the same for point A. The point A is effectively a cliff where no road goes on the other side of it. Check out the diagram below to see what I mean. The arrow means the line goes on forever in that direction.

What is the length of the altitude of the equilateral triangle below?
Mice21 [21]
B. 3 √3

The shortcuts for a 30 60 90 triangle is that the:

Hypotenuse is 2 times the short leg

The long leg is √3 times the short leg.

Making it 3 √3

Another way is by the Pythagorean Theorem.

a^2+b^2=c^2

3^2+b^2=6^2

9+b^2=36

Subtract 9 from both sides

b^2=27

Square root both sides

b=5.2 or the √27

√27 can be simplified more

An equation that equals to 27 that has a perfect square is 9*3


√9* √3

The perfect square of 9 equals to 3

So 3 √3

I need help plz help
amid [387]

We know

\boxed{\sf cos\Theta=\dfrac{b}{h}}

\\ \sf\longmapsto cos22=\dfrac{x}{47}

\\ \sf\longmapsto 0.9=\dfrac{x}{47}

\\ \sf\longmapsto x=47(0.9)

\\ \sf\longmapsto x=42.3
