Answer:
80 / 89
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, the following data were obtained:
<I = θ
Hypothenus = 89
Opposite = 80
Sine <I =?
Sine ratio of <I can be obtained as follow:
Sine θ = Opposite / Hypothenus
Sine <I = 80 / 89
Thus, the ratio of sine <I is 80 / 89

Answer:
8. 12 in
9. 30 ft
10. 87.92 in
Step-by-step explanation:
Quadrant 3 should have coordinates of (-x,-y)....therefore, his x coordinate has the wrong sign
X=mumber of boys
y=number of girls.
I suggest this system of equations:
x+y=30
x=4y
We can solve this system of equations by susbtitution method.
4y+y=30
5y=30
y=30/5=6
x=4y
x=4*6=24
Answer: there are 6 girls
