...I don't really get the question but 12.4 turned into a percent is 1240% lol
Answer: Ф = 20
Step-by-step explanation:
sin2Ф = cos (Ф+ 30 )
if sinα = cosβ , then α and β are complementary ,that is they add up to be
.
Therefore : 2Ф + Ф + 30 = 90
3Ф + 30 = 90
3Ф = 90 - 30
3Ф = 60
Ф = 20
144.4 is the answer when rounded of to the nearest tenth(1/10 or 0.1)
