<h3>Answer:
122 degrees</h3>
==========================================================
Explanation:
Angle BAC can be shortened to "angle A" since the letter A is in the middle.
Angle BCA can be shortened to "angle C" for similar reasoning.
We're told that angles A and C are base angles. For any isosceles triangle, the base angles are congruent
-----------
Let's use this fact to solve for x.
angle A = angle C
7x+1 = 5x+9
7x-5x = 9-1
2x = 8
x = 8/2
x = 4
Once we know what x is, we can find each base angle
- angle A = 7x+1 = 7*4+1 = 28+1 = 29
- angle C = 5x+9 = 5*4+9 = 20+9 = 29
Both angles A and C are 29 degrees each, so this confirms we have the correct x value.
-----------
The last step is to use the fact that all three angles of a triangle add to 180 degrees. This will help us find angle B, which is the vertex angle.
A+B+C = 180
29+B+29 = 180
B+58 = 180
B = 180-58
B = 122
The vertex angle is 122 degrees.
So we can say either angle B = 122, or we could say angle ABC = 122
"angle ABC" is the same as "angle CBA".

Answer:
$70.56
Step-by-step explanation:
Lets convert the mixed number (trip length) to decimal.
We know 3/5 (by long division) is 0.6, so 705 3/5th = 705.60 miles
Now, let's come to the problem:
1 gallon = 28.8 miles (mileage)
or
$2.96 = 28.8 miles
To find cost per mile, we divide:
That means, it costs $0.10 per mile
Since we want to travel 705.60 miles, we multiply to find the cost:
$0.10 per mile * 705.60 miles = $70.56
