Answer:
Radian angle = 1.154
Central angle = 66.123°
Step-by-step explanation:
Area of Sector, A
A = 1/2 * r² * θ ; θ measured in radian
A = 9 π
r = 7
9 π = 1/2 * 7² * θ
9 π = 24.5θ
θ = 9 π / 24.5
θ = 1.154 radian
1 radian = 57.296°
1.154 radian = (57.296 * 1.154)
1.154 radian = 66.123°
<em>There will be 6 buses passing before the meet to city B</em>
Answer:
-5 coach tickets
-8 first class tickets
Step-by-step explanation:
let x be the number of coach tickets and y the number of first class tickets:
Given that coach tickets costs $260 each, and first class tickets $1080 and that the total fare budget was $9940:
#From equation i, make x the subject of the formula:
#Substitute x in ii;
Hence, Sarah bought 5 coach tickets and 8 first class tickets.
The answer: a° = 180° - 62° = 118° , b° = 62° , c° = (180° - 62°) ÷ 2 = 59°
