Answer:
Jeremy's house is 4.5 inches far from his friend's house on the map
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The house of Jeremy's friend is 72 miles away from his home
∴ The actual distance between the two houses is 72 miles
∵ The scale on Jeremy's map is inch is equivalent to 8 miles
∴ Each miles on the map represents actual distance 8 miles
By using the ratio method
→ Map length : Actual length
→ inch : miles
→ : 8
→ x : 72
By using cross multiplication
∵ x × 8 = × 72
∴ 8 x = 36
- Divide both sides by 8
∴ x = 4.5
x represent the distance between the two houses on the map
Jeremy's house is 4.5 inches far from his friend's house on the map
Answer:
m∠B = 49.4°
Step-by-step explanation:
Use the law of cosines to get side c, and then the law of sines to get angle B
sin C/c = sin B/b
sin 99/7.543 = sin B/5.8
sin B = 5.8 sin 99/7.543
= .75945
m∠B = arcsin .75945 = 49.4°
