Answer:
The answer for number one is $5.21. NOT $6.25
Step-by-step explanation:
Answer:
ED ≈ 2.6 units
Step-by-step explanation:
Using the Sine rule in Δ DEF
= 
= ( cross- multiply )
ED sin115° = 6.95 sin20° ( divide both sides by sin115° )
ED = 
≈ 2.6 ( to the nearest tenth )
Distance = sqrt((6-2)^2 +(8-1)^2)
sqrt(16 +49)
sqrt(65)
8.06
round to 8.1 units
3x+4y = 15
4y = -3x + 15
y = -3x/4 + 15/4
y = (15 -3x)/4
answer is the first one.
1. y = (15 -3x)/4
