Question

PLEASE HELP!! DX
Mark the statements that are true

A. An angle that measures 2.5 radians is an acute angle.
B. An angle that measures 3.5 radians is an obtuse angle.
C. An acute angle measures less than 90.
D. An angle that measures 285 is a reflex angle.

Answer 1

To convert radians to degrees, you need to follow the equation radians*(180/pi).
Acute angles are less than 90 degrees
Obtuse angles are greater than 90 degrees.
Reflex angle is greater than 180 degrees, but less than 360 degrees.
A.) 2.5*(180/pi)= 143 degrees therefore the answer is false.
B.) 3.5*(180/pi)= 200 degrees therefore it’s true
C.) True because of statement above.
D.) 285 degrees is less than 360 degrees, but greater than 180 degrees. Therefore answer is true.
(All are true except the first one)
hope this helps! ;)

Answer 2

it's actually only c and d
