Answer:
w=20
Step-by-step explanation:
Solve for w by cross multiplying.
As an expression, it would be:
3 - 1/13w (or you could also do 1/13w - 3).
Angle of fire in degrees = 90 + 30 =120 degrees
Angle of fire radians =180 degrees = π
120* π/180=120π /180 OR 4π/6 OR 2π/3
Sin 35 = x/15
x = sin 35*15
x = 8.6 cm
0.4
4×1/10=0.4
multiply 4 by one-tenth
