g) 56.4 degrees
h) 230 degrees

Please help answer and explain 1 regular one and one decimal one!! IM CLUELESS TEACHER!!:(

Answer 1

Memorize this one:

180° = π radians

then 1° = (π/180) radians
then (whatever)° = (π/180)(whatever) radians

so 60° = (π/180)(60) = π/3 radians

56.4° = π/180 (56.4) = 47π/150 radians or appr .984 radians
