Cos(Ф) - 2sin(Ф).cos(Ф) =0
Factorize--> cos(Ф)[ 1-2sin(Ф)] =0
a) cos(Ф) = 0 ==> Ф= 0 or (0+2kπ)
b) 1-2sin(Ф) =0 ==> -2sin(Ф) = - 1 ==> sin(Ф) =1/2 Or
sin(Ф) = 1/2 ==> Ф =π/3 OR π/3 + (k+1)π/3
Answer:
39 acute isoceleleellsllelsls
Step-by-step explanation:
The angles of triangle always add to 180 degrees. So that angle on the bottom already takes up 102 so 180-102=78 and there are 2 angles left so both of those are 39 because 78/2=39 and 39 is an acute angle since its less than 90 degrees so ya
402,073,180 = 4.02073180 x 10^8
