<h3>
Answer: 29 miles (approximate)</h3>
======================================================
Explanation:
Segment AB is already given to be 19 miles long.
I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.
Use the law of cosines to find the missing side
a^2 = b^2 + c^2 - 2*b*c*cos(A)
a^2 = 12^2 + 19^2 - 2*12*19*cos(138)
a^2 = 843.874040417691
a = sqrt(843.874040417691)
a = 29.0495101579647
a = 29 when rounding to the nearest whole number
Side BC is roughly 29 miles long.
42/6 is 7 because seven 6s go in 42
Answer:
I think D
Step-by-step explanation:
Answer:
so its 50+.25(x) = y or 140. x is amount of minutes y is total
Answer:3 * (n + 4) = 93
3n + 12 = 93
Subtract 12 to both sides:
3n = 81
Divide 3 to both sides:
n = 27
