I believe this question is missing an image. However, I will just tell how how to solve such question and you can apply this solution to the triangle you have.
In any given triangle, the sum of the measure of the three angles must be equal to 180 degrees.
Therefore, for a triangle pqr:
measure angle pqr + measure angle prq + measure angle rqp = 180 degrees
If you have one angle given, then the sum of the other two angles will be equal to 180 - measure of the given angle.
If you have two angles given, then the measure of the third angle will be equal to 180 - the sum of the other two angles.
The table shows that every 1 hour he goes 12 miles so a variable would be 1h/24miles
Answer choice 3 is correct
The answer is 3x+18=147°, because a central angle is equal to the amount of degrees of its arc.
The scale factor 0.05 refers to length, so for area the scale factor is 0.05²=0.0025.
We then multiply: 220 ft²*0.0025=0.55 ft² (choice A)
