Step-by-step explanation:
According to the question, sin (0) is (-)ve
therefore, sin(0)= -15/17
AND , tan(0) = sin(0) / cos(0)
= 15/8
Answer:-16.25
Step-by-step explanation: do 17 minus 0.75 then add a minus
Answer:
90
Step-by-step explanation:
If we have total around 281 items, and we can divide them into groups of 3.
We can make around 281/3 groups which is about 90
Circumference = 2 x pi x radius
When circumference = 30, radius = 15/pu units.
Area of circle = pi x r^2 = pi x 225/pi^2.
Since we know pi is around 3.14, we can use that as an approximation and get the area of the circle with 30 units circumference to be around 72 squared units.
Hence, the circle with circumference of 30 units is much bigger.
