Using the law of sines,
sin80°/3.1 = sin∠QSR/2.4
∠QSR = sin^-1(2.4sin80°/3.1)
≈ 49.679°
∠SQR = 180° - 80° - 49.679° (angles in a triangle)
= 50.321°
sin50.321°/RS = sin80°/3.1
RS = (3.1sin50.321°/sin80°)
= 2.4 units (nearest tenth)
The length of line RS is 2.4 units.
Answer:
Step-by-step explanation:
Diameter d = 2.5 inches
Height h = 4 inches
Lateral area = πdh =π(2.5)(4) = 10π ≈ 31.4 square inches
Answer:
10 is maximum of packages of quesadillas.
Step-by-step explanation:
x= number of wings
y= number of quesadillas
x+y=20
8x+10y=$160
if x=7
then 7+y=20
20-7=14=y
14*10=140
8*7=56
Rasheed can't buy 20 packages, since it'll go over his budget.
So 160-56=104
And 104/10= 10 minimum
10*10=100
100+56=160
So he can buy 10 packages of quesadillas.
