What is the value of x?

Vladimir [108]

We know that

angle F=180°-(40+87)°=53°
applying the law of sines
EF/sin G=EG/sin F
EF=x
EG=13 cm
G=87°
F=53°
so

x/sin 87°=13/sin 53°---------> x=sin 87*(13/sin 53°)-------> x=16.3 cm

The answer is
x=16.3 cm

<u>Answer:</u>

$1972

<u>Step-by-step explanation:</u>

We are to find the minimum amount of money she will gross in eight weeks.

Number of hours of work in 8 weeks = $34 \times 8$ = 272 hours

Minimum amount of money she will earn in 8 weeks = $272 \times 7.25$ = $1972
