There is 2 midpoints on a line segment.
Answer: F=bill for first shop=4S-$630; S=bill for second shop
.
F+S=$3265 Substitute for F
4S-$630+S=$3265
5S=$3895
S=$779 ANSWER 1: The bill for the second shop was $779
.
F=4S-$630
F=4($779)-$630
F=$3116-$630=$2486 ANSWER 2: The bill for the first shop was $2486.
.
CHECK:
F+S=$3265
$2486+$779=$3265
$3265=$3265

Step-by-step explanation:
Answer:
The sum of a° and b° will be 180°.
Step-by-step explanation:
We know that two angles are supplementary when they add up to 180 degrees.
We also know that we know that a straight angle is said to be having 180 degrees. A straight angle does change the direction to point the opposite way.
i.e.
Straight angle = 180°
For example, a flat surface does have an angle of 180 degrees. Also, a straight stick does have a straight angle or 180 degree.
So, from the figure, the sum of a° and b° will be 180° as they add up to 180 degrees on a straight line and hence a° and b° are supplementary angles.
Therefore, the sum of a° and b° will be 180°.
