trigonometry:
Identify if the underlined word/s is true or false
If false change it to the appropriate one
A central angle of 114.6deg in a circle of radius 1 unit intercepts an arc of equal to 114.6units
114.6units is the underlined word

Best ResponseYou've already chosen the best response.0no need to do that , it's true since radius =1 , it is false if radius \(\neq 1\)

Best ResponseYou've already chosen the best response.2yes ... i agree loser66 ... but it;s the formal method... so i thought it would be better to say it first

Best ResponseYou've already chosen the best response.2@kaylala it is exactly as loser66 said.. since the raius is 1 unit... the arc is equal to the angle..

Best ResponseYou've already chosen the best response.0so my answer is in degree? 114.6deg?

Best ResponseYou've already chosen the best response.2u dont need to know the unit of the radius... because the unit cancel out since the radius and the arc length both belong to the same unit

Best ResponseYou've already chosen the best response.0but s=114.6units. not 114.6deg are those equal still?

Best ResponseYou've already chosen the best response.0is 114.6units equal to 114.6deg?

Best ResponseYou've already chosen the best response.2No. but the question says the angle is 114.6 degrees and the arc is 114.6units

Best ResponseYou've already chosen the best response.2it doesnt say 114.6 angle is equal to 114.6 unit

Best ResponseYou've already chosen the best response.0the formula is the length of the arc L = the angle * the radius. your radius = 1 if its unit is cm, then, r = 1 cm, right? if its unit is m, then r = 1m, right? If they don't use the unit of measurement like m, cm, km...., but "unit" then, the radius is 1 unit, right? so??? the length of the arc L = 114.6 * 1 unit = 114.6 unit

Best ResponseYou've already chosen the best response.0hence it's false? @Loser66 arc L is 114.6 unit and not 114.6deg???

Best ResponseYou've already chosen the best response.2no it;s not false ....

Best ResponseYou've already chosen the best response.2the angle has a unit ... so it's in degrees
