Answer:
C
Step-by-step explanation:
We know a straight angle is 180 degrees ( a straight line).
Looking at the figure, we can say that A + F + E = 180 (since it creates a straight line).
We know A = 45, E = 85, plugging these into the equation, we can solve for F:
A + F + E = 180
45 + F + 85 = 180
130 + F = 180
F = 180 - 130
F = 50
Answer choice C is right.

Examples :
2/x < 4 ....multiply both sides by x, cancelling it on the left side
2 < 4x ...now divide by 4
2/4 < x
1/2 < x
5/x + 7 > = 12
5/x > = 12 - 7
5/x > = 5 ....multiply by x, cancelling it on the left
5 > = 5x...divide by 5
5/5 > = x
1 > = x
Answer:
350km
Step-by-step explanation:
