Answer:
x = 36°
Step-by-step explanation:
The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:
5 * 2x = 360
10x = 360
x = 36°

Answer:
Step-by-step explanation:
Let b represent the amount Betty has. Then Ann has 2b+9 and together, they have ...
b + (2b+9) = 60
3b = 51 . . . . . . . . . subtract 9
b = 17 . . . . . . . . . . divide by 3
Betty has $17 and Ann has the other $43 of the total of $60.
Answer:
The slope is 3.75 OR 3 3/4.
Step-by-step explanation:
So the formula for slope I am using NOW, is based on the variables I named my dimensions. WARNING: NOT SLOPE FORMULA YOU MIGHT BE USING
y = 95 - 80
x = 10 - 6
Slope Formula: y/x
Substituted Slope Formula: (95 - 80)/(10 - 6)
Simplified Substituted Slope Formula: 15/4 OR 3.75
Hope this helps!!
Sorry i did not get your question bc there is no sign for + or -
