There is no solution. If there were to be one solution the lines would cross, eliminate the second one. If there were to be two solutions it would look like the attached picture below, eliminate the third one. If there were to be Infinity/many solutions then the lines would be on top of eachother, eliminate the fourth one​. Now, the reason why the answer is the first provided answer (No solution) is because the lanes are completely parallel. Thus, your answer is no solution.

<em>Note: The picture below explains why the third provided answer is incorrect </em>

n airplane took off from an airport and traveled at a constant rate and angle of elevation. When the airplane reached an altitud
hram777 [196]

The angle of the plane when it rose from the ground is 64.8 degrees

<h3>Application of trigonometry identity</h3>

Given the following parameters from the question

Altitude of the airplane H =  500m

Horizontal distance from airport "d"  = 235

Required

angle of elevation

According to the trigonometry identity

tan x = opposite/adjacent

tan x = H/d
tan x = 500/235

tan x = 2.1277

x = arctan(2.1277)

x = 64.8 degrees

The angle of the plane when it rose from the ground is 64.8 degrees

Complex numbers simplify square roots of negative numbers
Bogdan [553]

Lets do

\\ \sf\longmapsto \sqrt{-100}

\\ \sf\longmapsto \sqrt{-(10)^2}

\\ \sf\longmapsto \sqrt{10^2}\sqrt{-1}

\\ \sf\longmapsto 10i

Write in standard form

\\ \sf\longmapsto 10i

\\ \sf\longmapsto \boxed{0}+\boxed{10}i

(ILL GIVE BRAINLIEST!!)<br><br><br> What is friction and when does it occur?
docker41 [41]

Answer:

Friction is a force that opposes motion between any surfaces that are touching. Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. ... Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy

Colton has watched 222 comedy movies for every 333 other movies. He has watched 303030 total movies.
Sedaia [141]

The total ratio is 5

The number of comedy movies watched is 12

The number of other movies watched is 18

<h3>What is a ratio?</h3>

Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Therefore,

He has watched 2 comedy movies for every 3 other movies. The total movies he has watched is 30. Therefore,

  • 2:3

Ratio of comedy to total movies is as follows:

  • 2 : 5

number of comedy movies watched = 2 / 5 × 30 = 60 / 5 = 12

number of other movies watched = 3 / 5 × 30 = 90 / 5 = 18

Therefore,

total ratio = 5

number of comedy movies watched = 12

number of other movies watched = 18
