Answer:
BC = 18.34°
Step-by-step explanation:
Recall: Exterior angle formed by 2 secants = ½(the difference of the measures of the intercepts arcs)
Thus:
m<BAC = ½(DE - BC)
27.42° = ½(73.18 - BC) => Substitution
Multiply both sides by 2
2*27.42 = 73.18 - BC
54.84 = 73.18 - BC
BC = 73.18 - 54.84
BC = 18.34°
Answer:
12 because 1:2 so times 6 we get 6:12
Step-by-step explanation:
Answer:

Step-by-step explanation:
Using the formula for the surface area of a cylinder

As we know that r=3, h=5, and
=3.14 we can substitute in these values into the equation and then solve it
