Answer: The awnser is 45 degrees
Step-by-step explanation:
As you can see there are two z's which equal to 90 degrees and one z eqquals to 45 degrees.
This is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)
Answer: I'll give you formula
Step-by-step explanation: circumference = 2 x π x radius
radius = diameter÷2 area = π × radius²
Answer:
C
Step-by-step explanation:
In five minutes it decreased by 10 gallons (5x2=10), In 10 minutes it decreased by 20 gallons.
Given:
3:30 - 5:30 = page 160
5:30 - 8:00 = page 280
280 - 160 = 120
8:00 - 5:30 = 2.5 hours or 5 half hours
120 / 5 half hours = 24 pages every half hour or 30 minutes
3:30 - 5:30 = 2 hours or 4 half hours
24 * 4 = 96 pages
160 - 96 = 64
P Casey was on page 64 at 3:30 p.m.
