Answer:
Step-by-step explanation:
Remember that sine is the ratio of the opposite side to its hypotenuse:
For D, the opposite side to D is 28, and the hypotenuse is 53. Therefore:
Or, in decimal form:
Likewise, the side opposite to E is 45, and the hypotenuse is 53. Therefore:
And using a calculator:
Answer:
7.80
Step-by-step explanation:
46.80 divided by 6 is 7.80
Answer:
780miles.
Step-by-step explanation:
D=S*T
D=130miles/hour*6hours
D=780 miles
Answer:
49
Step-by-step explanation:
This is because 49 is below 50 but above 40. The number must also round to 0 from the nearest 100, so any value 50 and above will round to 100 and any value 49 and below will round to 0. So we are left with the values 40-49 because any value below 40 is rounded to either 40,30,20,10 or 0. Since any value below 45 won't round to 50, any value between 45 and 49 will work.
Answer:
Step-by-step explanation:
we can find the equations for both lines and analyze after
AB:
CD:
Determining whether two lines are parallel or perpendicular involves looking at their slopes. AB has a slope of -2/5, CD has a slope of -5/2. Since these are not equal (not parallel) and not negative reciprocals of each other (not perpendicular), the lines are neither perpendicular or parallel.
