Answer:

Height\ of\ monument=555.5\ ft

Explanation:

In\ the\ digram\ AC\ is\ the\ monument\ and\ DE\ is\ the\ student.\\\\AC=AB+BC\\\\Let\ AB=x\\\\BC=Height\ of\ the\ eye\ of\ the\ student=DE=5\ ft\\\\\Rightarrow AC=x+5.................................eq(1)\\\\Student\ is\ standing\ at\ a\ distance\ of\ 25\ ft.\\\\CD=25\ ft\\\\BE=CD=25\ ft\\\\Angle\ of\ elevation=87.4\textdegree\\\\\angle AEB=87.4\textdegree\\\\Now\ in\ \triangle ABE\\\\\tan \angle AEB=\frac{opposite}{adjacent}=\frac{AB}{BE}\\\\\tan 87.4=\frac{x}{25}\\\\x=25\times \tan 87.4\\

x=25\times 22.02171001\\\\x=550.54275\ ft\approx 550.5\ ft\\\\Height\ of\ monument=AC=x+5\\\\Height\ of\ monument=550.5+5\\\\Height\ of\ monument=555.5\ ft

Dinosaurs once stomped across the Yukon, leaving tracks in mud that were buried in more mud and hardened to stone. Some may have
densk [106]

In this question, we are not provided with the image of the dinosaur track. Because of this, we are unable to tell whether this specific track is right-side up or upside-down. However, we can give you some guidance so that you can identify this on your own.

In general, in this type of prints, mud cracks extend downward into soft sediment. These cracks mean that when more sediment is washed in, the second layer fills the cracks beneath. Afterwards, once the layers have hardened, the rock may be cracked apart. Based on this, we can conclude that if you see troughs in a mud-crack pattern, you re looking at the second layer, which was originally right-side up.

Is relative humidity or dewpoint a better variable to examine to determine if there is sufficient moisture for thunderstorms to
skad [1K]

Answer:Relative humidity is a better

measure

Explanation:

Why? Because relative humidity measures the amount of moisture in the air compared to the current temperature of the air and what it can hold at that point. While few point merely measures the temperature of the air at which it reaches dew point and dew falls. . The basic conditions for a thunderstorm are moisture, unstable air and lift. It would be easier to read off moisture level in the air since relative humidity at 90 to 100 means it will rain more certainly than it will with dew point which may only mean that dew will fall.
