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.
5 m by 10 m
5+5=10 and 10+10=20
10+20=30 which is the full perimeter
Answer:
3 1/3 or 3.3(repeated)
Step-by-step explanation:
2/3 ÷ 1/5
= 2/3 × 5
= 10/3
= 3 1/3 or 3.3(repeated)
