Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Answer:
the number is -39
Step-by-step explanation:
2(n-6)=3(n+9)
2n-12=3n+27
-2n -2n
-12=n+27
-27 -27
-39=n
Area of base = 9pi
curve surface area = 3*pi*15=45pi
total area 54pi
i guess the n here represents pi the answer would just be a since its the most relevant
