Answer:
20 degrees
Step-by-step explanation:
Since angle B and angle A are both inscribed angles to the same arc, they must be equal. Therefore:
7x-8=5x
Subtract 5x from both sides:
2x-8=0
Add 8 to both sides:
2x=8
Divide both sides by 2:
x=4
Now, you can plug this back into the equation for angle B:
B=7(4)-8
B=28-8
B=20
Hope this helps!

Step-by-step explanation:
First I would break it down int 50 + 4 but either way you divide both by two
Answer:
A
Step-by-step explanation:
If you plug them in you get 2≥-1
<span>The volume of a cylinder is the area of the base (π r^2) times the height (h). So it's V = π r^2 h. HOPE I HELPED</span>
The average speed = (speed 1 + speed 2)/2
the average speed = (80/10 + 100/20)/2
the average speed = (8 + 5)/2
the average speed = 13/2
the average speed = 6.5 km/minute
