BAD=86
BAD + ABC= 180
(8x+22) + (12x-2) =180
x=8
BAD = (8 x 8 + 22)
8 x 8=64
64 + 22 = 86
Square out the quantity (sin + cos) and look at all the pieces. You'll find pieces equal to '1', and a piece equal to sin(2x).
Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
