Step-by-step Answer:
Two ways to find the answer.
1. Using sine rule, we have
d/sin(D) = f/sin(F) (d=EF, f=DE=3)
cross multiply and solve for d:
d=f*(sin(D)/sin(F) = 3*sin75/sin50 = 3.783.
2. using the theorem that if angle D is greater than angle F, then the length of the opposite side of D is also smaller than the opposite side of F.
Here D>F, so d>f. The only answer choice greater than 3 is 3.8, so there.
Answer:
k = 55
Step-by-step explanation:
First clear the fraction by multiplying all three terms by 5. We get:
k - 10 = 45
Adding 10 to both sides results in
k = 55 (after having combined like terms)
6+3w (don't mind this it has to be 20 characters long)
10L/100km(1.6km/1Mile)(1gal/3.7854 L)=16 Gallons/378.54 Miles=
23.7 Miles/Gallon
