Answer:
sin(B) = 2/3
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side.
sin(B)/b = sin(A)/a
sin(B)/8 = sin(30°)/6 . . . . fill in the given values
sin(B) = 8(1/2)/6 . . . . . . . .multiply by 8
sin(B) = 2/3
Answer:160 miles
Explanation:
You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.
If you set out the steps with short sentences it will be clearer.
On 15 gallons, a car can travel 400 miles÷15↓
On 1 gallon, a car can travel 400÷15=262
miles
Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.
On 6 gallons the car can travel

Answer:
14•4°
step by step explanation:
ratio=1:2:3=6
angles in degree=150°
6/150°×360°(simplify)
6/5°×12°
=72°/5°
=14•4°
The largest angle=14•4°

Answer:
1: 75
Step-by-step explanation:
20cm : 15m
Convert meters to cm
1 meter = 100 cm
15m = 15 x 100 = 1500 cm
20cm:1500cm
Divide both sides of the ratio by 20
=> 1 : 1500/20 = 1: 75
