Answer:
Approximately 54°
Step-by-step explanation:
So we know Angle A, the side opposite to Angle A, and the side opposite to Angle B (the angle we want to find). Given these circumstances, we can use the Law of Sines.
The Law of Sines states that:
The variables do not really matter. Instead, it's more important that the angle corresponding to the side lines up with each other.
Anyways, since we know Side A, Angle A, and Side B, let's use the first and second ratios:
Plug in 80° for A, 11 for a, and 9 for b:
Cross multiply to solve for B:
Divide both sides by 11:
Use the inverse sine function. And finally, use a calculator to solve:
Answer:
x= 8
Step-by-step explanation:
Answer:
10 is your answer.
Step-by-step explanation:
Both 843 and 84 will be turned to 800/80 because 4 is below 5 so it will be turned into a zero and the 8 left an 8.
800/80=10 is your answer.
Speed is distance divided by time. First you have to find the total distance, so you would do (50*3)+(65*.5)+70(1). After you get that answer, you divide it by the time which would be 3 hours+.5 hours+1 hours. Just remember s=d/t.
