cos(33^{\circ})

Step-by-step explanation:

Given

sin(57^{\circ})

Required

Determine an equivalent expression

In trigonometry:

sin(\theta)= cos(90^{\circ} - \theta)

In sin(57^{\circ})

\theta=57^{\circ}

Substitute 57^{\circ} for \theta

in sin(\theta)= cos(90^{\circ} - \theta)

sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})

sin(57^{\circ})= cos(33^{\circ})

Hence, the equivalent expression is: cos(33^{\circ})

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
