Answer:
60° =
radians
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × 
Thus 60° in radian measure
= 60 ×
( divide ( cancel) 60 and 180 by 60 )
=

Answer:
t+5
Step-by-step explanation:
We can combine like terms, and get t+(4+3-2) to get t+5.
Hope this helped!
Answer:
x + 4y = 4
4y = 4 - x
multiply both sides by 1/4
y = 1/4( 4- x)
y = 1- 1/4x
