The interior angles of a polygon are; (3x + 30), x, 2x, (x + 20) and 3x. find the value of x

julia-pushkina [17]

Answer: 49

Step-by-step explanation:

This polygon has 5 sides, meaning its interior angles add to $180(5-2)=540^{\circ}$ .

$3x+30+x+2x+x+20+3x=540\\\\10x+50=540\\\\10x=490\\\\x=49$

A person standing at the top of Mountain Rainier would be approximately 2.7 mi high. The radius of earth is 3959 mi. What is the

astraxan [27]

Answer: $146.2\text{ miles}$

Step-by-step explanation:

Given: The approximate height of Mountain Rainier h= 2.7 miles

The radius of earth = 3959 miles.

Let d be the distance to the horizon from this point.

We know that the line of sight to the horizon , the radius at the horizon and the radius at the mountain from a right angle triangle.

Therefore, by Pythagoras's theorem we have

$d=\sqrt{(R+h)^2 - R^2}\\\\\Rightarrow\ d=\sqrt{(3959+2.7)^2-(3956)^2}\\\\\Rightarrow\ d=\sqrt{(3961.7)^2-(3956)^2}\\\\\Rightarrow\ d=\sqrt{15695066.89-15673681}\\\\\Rightarrow\ d=\sqrt{21385.89}\\\\\Rightarrow\ d=146.23915344\approx146.2\text{ miles}$

Hence, the distance to the horizon from this point= $146.2\text{ miles}$
