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
Answer: B) -48
Step-by-step explanation:
If the system of two linear equations
has infinitely many solutions , then

For the given system of linear equations : 
We , will have

The value of 
Hence, the value of rs is -48.
Thus , the correct option is B) -48.
Answer:
B
Step-by-step explanation:
Answer:
okay, so you put 14/20 as a fraction, and find out the percent. that is 70%. then you find 70% of 100, which is 70.
Let x be the value of the his purchases without the discount. The $64 is the value of the 32% discount.
64 = 0.32x ; x = 200
Thus, he should have paid $200 if there was no discount. The amount he paid (p) is only 68% of this value. p = (0.68)(200) = 136. Hence, he paid only $136.
