Answer:
A= 40°
B= 35°
C= 15°
Step-by-step explanation:
Since it says if the triangles were accurately drawn, then A would be the same degree as Q. C would be the same degree as P. B would be the same degree as R. Since R's degree is missing I knew that a obtuse triangle was 90°. I added 40+15 and got 55. Then i subtracted 90-55 and got 35. So the unknown value would be 35°.
I hope this helps.
.72
.725 would be less because it has more behind the decimal.
.72 would be more because there are only 2 numbers behind the decimal
The cost depend on the number pencils, so the cost is the y and # of pencils is the x
Same as for question 7
To graph, the length depend on the time, so length is y, time is x
6. Linear
7. Not
